Fixed importing params (remoevd extra /)

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.)

- 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

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

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
