Fix /cheat command not researching all valid technologies.

[heinwessels]

Fix the /cheat command to actually research all technologies. It doesn't research inifnite levels very far, and ignores the victory tech.

Only caveat is that it will research all techs even if it's the first console command entered by the player, when the console still says "Repeat the command to proceed". I couldn't find a way around this.

I'm not a modding expert but it seems there's an event that can be used to check if the cheat command was actually run.
I guess the first time the command is entered, the event is not called as cheat mode is not enabled.

Also it would seem the command called when enabling cheat mode is "research all technologies", which can be called separately in the console and will not be fixed by this pull request

Sorry it took me so long to look at this. I'm not sure why research_all_technologies doesn't work (probably the hidden/disabled techs?), but using the cheat event sounds like it'd be good at least.
