Fixing bug with Contenttype returned

Adding named graph on default service

Removing no html queries from models/type.rdfs:Resource/

among other bugs

Adding debug option to lodspk.sh
Moved modules to classes/

Using ASK instead of select
using [] instead of variables in query

Also, moved `util/ldspk.sh` to `util/lodspk.sh` for consistency

Adding url decode Filter
Fix passing parameter issue in service module

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.

Fixing https://github.com/alangrafu/lodspeakr/issues/28

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

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