We cannot just remove data from common.inc.php
The class expect and try to use it throwing errors/warning every
time the application load.

- Require the application default settings. Loadspkr needs it
and have to stop if not present and not simply throw a
notification.
- Introduce a constant that points to where Loadspkr have been installed. Allows
us to later move the common.inc.php without it breaks the bootstrap.

Full autoload the application boostrap process.

Addressing a old legacy bug. Making sure the file validate also make it
easier to spot newly introduced errors and bugs.

We should not trust language " auto magic". Let us
be sure we do a strict type check.

- Paves way for real autoloading in the future.

- HTML element deprecated should no longer be used.
- Generic reformatting.

- Always called utilities. We need to make sure they work
as expected. Introduce PHPUnit tests.
- Due to the use of gobals inside the static methods they
become untestable. Remove use of global but that also
forces a change if method signature.

- Always run and should be fast.
- Introduce tests to make sure I actually work.
- Stop method from using global states to make it testable and safe.

- Fix static linked ARC2 lib in module code.
- Fix typo in index.php

- PSR4 autoload all classes except modules.
- Explicit declare what is used by classes.
- Composer define what PHP modules are used.

GUI implemented

TODO: GUI needs work

Adding user agent LODSPeaKr

Now looking by type and the special pages are modules.

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)

Fixed importing params (remoevd extra /)
