Implement meta-classes for UI hints

The following meta-classes are implemented and placed to the core
library: Title, Description, HelpText, Hidden, Section, Position.
They can be attached to the different MuranoPL entities and used
during the automatic UI definition generation.
Also meta-class ModelBuilder is added for marking special static
methods.

Change-Id: I474d69b2cadb9b200e70d4d9daaef3e87d9cb3a5
Partially-implements: blueprint muranopl-forms
