Tidy up APILookups

- Fake functions (eg. gtk_text_iter_new)
- "..." as arg type in gtkds/* files.
- support for nocode: (dont generate the code, unless jscode exists for it..)
    (generate links/proto if pos. though)
    
Static Methods
(eg. Gtk.Image.newFromPixbuf(....))
=> add newFromPixbuf as a property of the constructor..

Enums

Structs :: property getters?

Methods that use Structs - could use std. objects...


Specific Structs: TODO:

Gtk.initMultiThread : multi thread init!? - sould init be done automatcially anyway?
Gtk.Image : new with different constructors.
Gtk.TextIter: constroctor borked.
Gtk.TextBuffer: broken due to Iter I think.
Gtk.TreeView/Iterator: sort out interface and node implementation.
Gtk.ListStore/TreeStore
Gtk.ComboBox[Entry]? 

Gtk.MenuItem*** Working on it..
