bug fixed: cut_scene didn't work ("nicely done!" in chapter 1, for example)

bug added with commit 326953bf9431e5fc9ca225128ac897bb44d86d8f
added a console key (backquote, the key below escape) to enter commands like "add_units" or "victory"

From the manual: Backquote (the key below Escape): console command (only in single player mode). The only useful commands at the moment are add_units (to get units or buildings instantly) and victory (to win, for example to skip a chapter). Example of a "add_units" command: "add_units a1 100 archer".
modding: it is now possible to use the word "faction" instead of "race"

For example, in rules.txt:
def orc_faction
class faction
