Problem is is with operator redo which click-extrude exposed. Check if redo operator can run, otherwise lock the UI and add a label that the operator doesn't support redo. This is clunky but IMHO better then failing silently and leaving the user confused. - Merged redo functions into ED_undo_operator_repeat(), code was duplicated in a few places. - added WM_operator_repeat_check to check if WM_operator_repeat() can run, avoids an undo call when redo work. Unrelated changes - GHOST_SystemWin32.cpp set to utf8 encoding. - cmake_consistency_check.py now checks source files are utf8.
