Service now return 406 if service exists but the content type is not
supported

Fixed use of previously returned values in classModule

Adding new format for ref:Resource

Delete old format

Now looking by type and the special pages are modules.

Haanga doesn't support variables starting with 'end' (reported at
https://github.com/crodas/Haanga/issues/14)
Use of {{base.sparqlendpoint.local}} in the meantime

Adding better error report when sqlite is not writeable.

Instead of returning to ".." it will go to $conf['home']

* Back to "first" instead of "f" to increase readability
* default views and models are now rdfs:Resource
* 'use_external_uris' renamed to 'mirror_external_uris' to increase
readability
* When mirroring URIs, LODSPeaKr will include two triples using
(owl:sameAs and  con:prerredUri) from mirrored URI to original one

Now using f[.model]*.variable.value

TODO: still buggy (example: dbpedia)

When only the first value is needed (or expected) instead of iterating
over the array, it is possible to access the values by adding "_first."
before the variable name.

Example: {{r.modelFile._first.varname.value}}

Instead of

{%for row in r.modelFile%}
{%if forloop.first%}{{row.varname.value}}{%endif%}
{%endfor%}

Fixed importing params (remoevd extra /)

Also, moving script as a class to 'classes'
fixing bug in Utils
creating static dir

TODO: include app-level params, such as root, as well as provenance
data (where was this application originated, at which time it was
collected, etc.)

Working: strings with q values as well as only acceptable content types
Still missing: consider case of level string

Is annoying to iterate when I know I will get only one result, so for
the first row retrieved it is added at

```
r[.FILENAME]+.first.VARNAME.value
```
Also: Fixed small bug in default view

Also, fixed typo in configuration

- Added debug flag, when `true` returns in page SPARQL query as well as
results array

Right now, when http://example.org uses data with namespace
http://another.com
- Every time a SELECT is executed, it will change http://another.com to
http://example.org.
- This is not the case for DESCRIBE/CONSTRUCT
- N-Triples, Turtle and RDF/XML versions works fine so far

Problems:
- No description for new URI in http://example.org
- Not clear how to link URI in http://exampler.org to
http://another.com. Suggestion: `<http://example.org/abc> owl:sameAs
<http://another.com/abc>` . It is no clear __when__ to do it

instead of {{r[.INNERFILE].value.VARIABLE}}

now it will be {{r[.INNERFILE].VARIABLE.value}}

Allow multiple/recursive queries
Allow use of multiple endpoints
Modified query tu support Haanga syntax
Fixed several bugs

Model definition:

The new structure will be

models\
           |
           |
           \foaf:Person.model.html\
                                              |
                                              |
                                              \localQuery1
                                              \localQuery2
                                              \dbpedia\
                                                           |
                                                           |

\queryInDBpedia1

\queryInDBpedia1

Queries under the type subdir will be executed against the default
sparql endpoint
Quries under a subdir named an endpoint shortcut(*) will be ran against
that endpoint

(*) You need to define an endpoint in settings.inc.php

to query against your endpoint you need to define
$conf['endpoint']['mySparqlEndpoint'] = 'http://example.org/sparql';

Sparql endpoints are already defined for dbpedia and logd

Later you can create a subdirectory called 'mySparqlEndpoint' under a
model.

By aware that it is HIGHLY recommended to use only letters and numbers
(no periods, colons, etc.)

Silly mistake: blank line at the end of file led to wrong RDF/XML (because document didn't stated w/ XML header

Adding templates dir
Removing owl:Class view and model to allow ln form rdfs:Class

Also, displaying results when there is only one class in special/index

Instead of iterate over a row like {0.000000or row in
r.filename}{{r.value.variable}}{4.659039e-321ndfor} when there is only
one row, it is possible to access the values from
{{r.filename.value.variable}}

Instead of creating a file for the model, create a dir (e.g.,
foaf:Person.view.html). Inside add different files (the name doesn't
matter). In the view file, they will be accessed as r.filename and can
be operated as usual

Instead of creating a new class, users only need to create a model and
view file called special.<COMMAND>.[view|model].extension  Thus, it is
possible to create new URL such as http://<HOMEURL>/special<COMMAND>
