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.

* 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

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.)

Also, fixed typo in configuration

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 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

Adding namespace.php including all namespaces available from
http://prefix.cc

Removed functions related to extract  metadata from a SPARQL endpoint,
it stores it on the sqlite database. This will ease the installation
process

First stable version
