[FEATURE] Add FAL support

Add FAL support for Domain models, NewsimportService,
fluid templates and ViewHelpers.

The new properties are FalMedia and FalReleatedFiles.

Enabling FAL is posible in EM. It is posible to
use old and new behaviour and FAL + news Multimedia element.
Default templates will try to render the old media items
when no FAL media items are found.

The NewsImporter will only copy files if they are not in
a storage. Otherwise is will just create a reference to
the existing file.
Importer now also supports MEDIA_TYPE_MULTIMEDIA.
Use https://github.com/fsaris/news_ttnewsimport for Ext:DAM
support while importing.

Works only on TYPO3 6.* branches.
