comment out temporarily, the chat and other gui calls

since that'll all get stripped out and repurposed towards qt.

chat also needs to be stripped into model/view, much like quickbarinventory
already does.
try to reinstate rendering and other things, but poll()/tick()

isn't getting called because our main loop/accumulator is borked now.

wondering how i can  nicely do that, preferably running on the same qt thread
...or maybe not?
begin merging and restructuring game -> client handling, for qt progress..
event loop transition is in much better shape now

looks like the render window expires though, so gotta fix that.

then after that i need to make the client main entrance on its own thread
and have the client rendering take place *only* from the qt event thread,
and do some simple big locking there (which should be sufficient i guess).
