Fixing adding triples when external URI was off

Fixing bug with Contenttype returned

Adding named graph on default service

among other bugs

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.

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.

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)

When only the first value is needed (or expected) instead of iterating
over the array, it is possible to access the values by adding "_first."
before the variable name.

Example: {{r.modelFile._first.varname.value}}

Instead of

{%for row in r.modelFile%}
{%if forloop.first%}{{row.varname.value}}{%endif%}
{%endfor%}

Fixed importing params (remoevd extra /)

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

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.)
