Add support for select-all(), cut(), copy() and paste() functions on text input elements (#2804)

Browse source 
In the compiler this is still very primitive, but an attempt to start a
generic interface. The basic assumption is that all item functions will
eventually need access to the window adapter and itemrc. Support for
additional arguments is still missing.

Also missing is support for the function access via rtti in the
interpreter, hence the hardcoding at the moment.
