GUI implemented

TODO: GUI needs work

Adding user agent LODSPeaKr

Now looking by type and the special pages are modules.

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)

Fixed importing params (remoevd extra /)

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

Also, adding content type to turtle

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.)

If
```
ex:resource a ex:Class1, ex:Class2, ...
```

LODSPeaKr will try to use the first one of them available

- 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

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.)

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

- Added "special" URIs where an API can be created -- Included an
abstract class from where these special URIs can be implemented --
Included a basic class that implements the abstract class -- So far,
only listing instances for a class is implemented - Root for website
redirection -- Now it goes to /special/index to list all classes - Moved
include of settings below in commons.inc.php so it can override values -
Created owl:Class and rdfs:Class' templates
