bugfix for herosoldiers

added another securitycheck for classes without TC abilities

- fixed Psi-Ops loosing 2 abilities if xNormalizeAbilities was enabeld
- see mod-page on how to get those abilities back

fixed changelog button location

- The additonal abilities for herosoldiers got moved to a seperate mod, check the mod-page for the link
- Added a new interface for the extension-mod to enable / disable abilities for crossclassing
- xNormalizeAbilities default state in the config has been changed to false
- xNormalizeAbilities also removes abilties if your herosoldiers surpasses 'XComHeadquarters_NumAWCAbilities'
- Don't forget to make the changes to your config again

I've shifted around alot of code to make debugging and improving this mod in the future way easier and faster for me.

Therefor if you previously made changes to the config-file you most likey have to redo them, i tried to comment each setting as much as possible.

Furthermore xFillUpMissedAbilities is now called xNormalizeAbilities and will still fill up all your soldiers abilityslots to XComHeadquarters_NumAWCAbilities specified in XComGameData.ini (included in this mod). BUT it also removes a number of random abilities by the margin it exceeds XComHeadquarters_NumAWCAbilities, meaning if you have a herosoldiers with 5 or 6 x-com abilities it will be tuned down to XComHeadquarters_NumAWCAbilities (default is 4). So some players may expierence a loss of abilities.

Your soldiers get normalized everytime you load your savegame and herosoldiers gets normalized on recruiting. Classmods which utilize 4 trees will most likey only get updated between loading savegames if the the author of the classmod does not call the recruited alert as herosoldiers do. So you might get a class with more abilities but will lose them during loading a save.

The additional abilities I've added for herosoldiers of course stay and feel free to add more in the config to your likings.

I have tested the new functions extensivly but there is always the possibility that I overlooked something. If that is the case plz post a comment and be as detailed as possible in what happend.
