Several clean ups in the source code root. Removed unused files.

The subproject libutils was renamed to pgmutils and now resides on libs/

The subproject libparsers was renamed to pgmparsers and now resides on
libs/

The subproject libpgmodeler was renamed to pgmcore and now resides on
libs/

The subproject libpgmodeler_ui was renamed to pgmui and now resides on
libs/

The subproject libobjrenderer was renamed to pgmcanvas and now resides
on libs/

The subproject libparsers was renamed to pgmparsers and now resides on
libs/

The main executable subproject was renamed to gui and now resides on
apps/

The main-cli executable subproject was renamed to cli and now resides on
apps/

The crashhandler subproject was moved to apps/

Created a subfolder called assets and it contains all deployed files
that aren't libraries or executables: conf, lang, schemas, samples, etc

Refactored all .pro/.pri files in order to reference pgModeler libraries
from variables $$PGM[LIBNAME] instead of relative paths.
