Small bugfix for the Update 2.0.3

Some bugfixes
- solved a Bug with wrong garrisons in Karak Eight Peaks for Greenskins and Dwarfs
- Howitzers are now recruitable in campaign (forgot to add them)
- small rework of the recruitment of units by Empire and Dwarfs, now it makes more sense

I haven't tested it, because the changes are relatively minor.
Please report if anything isn't working.

Small Bugfix, the projectiles of the Howitzers dissappeared when shot at full range, I changed the expiry_value of the projectile, should work now.

Corrected some mispellings in the loc-files.

the biggest and final Update for this mod!

for a list of all Units after Update 2.0 go here:

- fully implemented Bretonnia with 10 new units, most identical with Emp, but with new models
- 6 new units for WE to counter firearm units with new developed Magic Arrows and Shields
- 8 new units for Chaos, some Chaos Dwarf versions of Dwarfen units, some unique units
- 3 new units for Vampires (Blood Guard, Blood Guard Cuirassiers, Zombie Runners)
- 2 very strong artillery units: Dwarfen Howitzer and Empire Howitzer
- Units for Wood Elves and Vampires won't change their gameplay significantly, I don't want to make more firearm army clones, but want to conserve their lore, the new units are limited and will be rare elite units
- many existing models have been reworked to look more interesting and more diverse
- Overhaul of existing Wood Elf units, Tree spirit units are more protected against firearms
- Wood Elves will start with a little bit more amber to recruit more Tree units
- Empire General overhaul: Empire generals and Captains will look more like modern Generals, using heads of other units like Pistoliers or Free Company, Unit cards and portholes are changed too
- Square formation for some firearm units: Units will close ranks, effective against Cavalry charges
- Wide square formation for Free Company + halberdiers: to protect Artillery or Generals inside
- Circle formation for some Misile cavalry units: Like the Cantabrian Circle of old Total Wars
- reworked difficulty, Mod should be a bit more challenging now
- Rework of Steam Tank, Gyrocopter and Gyrobomber
- better UI flags to help you in using and recruiting the right units
- Reworked recruitment buildings for Empire and Dwarfen units, to help AI recruit them and to make it a bit more logic
- many more small changes and bugfixes

I tested this update for many hours, however, if anything crashes or seems to be strange, please report! :)

- Update for the Bretonnia FLC
- I had to delete the possibility to recruit any firearm units for Bretonnia, as it crashed the game (maybe because of the new peasant mechanic)
- I will have to implement completely new units for Bretonnia, this will happen together with the Update for the Woodelfs
- Garrisons of Bretonnia still contain some firearm units

- hopefully this fixes sound bugs with RoR in battle

- hopefully this fixes sound bugs while in battle
- maybe fixed another crash while mouser-over at the Goblin workshop (couldn't recreate the bug)

- fixed a bug with non-appearing Wood Elf Garrisons

- Update for the Wood Elves DLC

Had to copy some values into another table. I am 99% sure that everything was copied correctly, but if anything doesn't works, crashes or seems weird please report :)
