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 {{base.endpoint.local}} works

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.

Move special/index to special/classes
Added special/namedGraphs

* 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

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

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

Also, fixing error in default template

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 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

Created symlinks to default.*.rdf so we have a unified query/view for
each format (although it still can be modified, but is a bad practice)

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>

- 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

small issue with the html namespace fixed

Fixed lodspeakr dir as 'lodspeakr' css is not moved views will include
loudspeaker in the css path

First stable version

renaming files in view and models

Creates HTML based on Haanga
Added basic stylesheet (but needs more work)
Default template returns RDFa

Notes: Tested using ARC2 and 4Store and works out of the box
