Blender Git Loki

fixes for errors on startup and compiler errors and draw speedup.

* Drawing the console text now skips all lines outside the view bounds.

* Added dummy C operators for console.exec and console.autocomplete so blender wont complain at startup, its not really a problem but people testing reported it a few times. Eventually we should have some way python operators are initialized before the spaces operators are checked.

* reordered the imports so the "ui" dir is imported before "io", for now this means bpy.ops is defined before exporters and importers need to use it, was causing a python error on startup.

* fixed all compiler warnings for the console (gcc4.4)

* stopped operators were printing out the return flag.

* removed references to ACT_OT_test, TEXT_OT_console_exec and TEXT_OT_console_autocomplete
