Add 5.0 support

[mepeisen]

Changes see http://docs.sencha.com/extjs/5.0.0/whats_new/5.0/whats_new.html

Relevant changes:

• [Code completion] components with "bind" config (to connect models to a setter)
• [Code completion/ Type] View Controllers. They are tied to a view. So the ref etc. config can be view specific.
• [Code completion] Components -> reference. this.lookupReference.
• [Code completion/ scope] item listeners by name (is it incompatible to extjs 4.x?)
• [Code completion] Fomulas: at component bind value, at Formulars, see examples from extjs changes page
• [Code completion]: field types (Special alias variant)
• [Code completion]: bind Validation
• [Code completion/ types]: private methods

other changes (is any Support needed?)

• Routing
• new layouts
• Responsive configs
• new reference handling in models
• chained stores
• mashups (nice feature but I don't see any point for an IDE code completion etc.)

I will add the 5.0 facet Version as soon as possible
