[admin] Incorrect navigation type selected.
TinyMCE was not initialized correctly.
Merge remote-tracking branch 'origin/master'

Conflicts:
	modules/core/app/main/origo/core/interceptors/forms/TinyMCEEditorProvider.java
Removed AliasNavigation (it's automatically handled when linking to a page with an alias).
Renamed some Providers to follow a common pattern (might need to rethink).
Updated most types to use a static string field from the object instead of string to keep it more refactoring proof.
