Ported Gideon core to KTextEditor interface

[Harald Fernengel]

Hi,

okay, my third rewrite now works:

http://www.bnro.de/~harry/gideon/

as you can see I commented out quite a bit of code, but that's only a matter 
of changing KEditor calls to KTextEditor calls and should be quite trivial.

What works: You can use any editor that implements the KTextEditor interface 
(currently hard-coded to Kate :))

What doesn't work: Most of the parts, they have to be changed to KTextEditor 
first and anything that includes more than opening, changing and closing a 
file ;)

Consider this a proof of concept that KTextEditor actually works in Gideon 
without too heavy code changes.

The road ahead: Finish this patch, change all the parts to KTextEditor 
interface, finish the KTextEditor document/view manager.

Roland: If KDevelop 2.2 operates on KTextEditor, it would be very easy to use 
Gideon parts also for KDevelop 2.2. Also, do you think we could use my 
generic doc/view manager in both branches (if it gets a bit more mature...)?

Best regards,
Harry
