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

Now {{base.endpoint.local}} works

Adding better error report when sqlite is not writeable.

Move special/index to special/classes

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'
