Fixed some errors in the german version

Included a working german version!

Included an unfinished dutch version for testing

Updated this for Rise of the rajas support (if you accidentally have this selected while on the expansions dataset, it will at least show new units corectly, for old units it might have outdated info though)

Mostly style fixes, I changed the wording on some parts, made capitalization more consistent (classes and unit names are capitalized, everything else subject to normal english rules)

Some small typo fixes and similar stuff.

I fixed an error where the tooltip for farms said they contain (225/350/525) food with upgrades instead of the correct (250/375/550).

I also returned the Saracen's archer anti-building bonus description back to the original +1/+3 instead of +2/+4. The latter is technically correct, but due to the way damage is calculated in aoe and the high pierce armor of buildings, in effect it's almost always +1/+3, so the other values might be misleading.

The tech tree was missing the free town watch bonus for the byzantines.

Expansion support (if this mod is played on expansions by accident): Changed some UU descriptions where the elite counter part was missing the "elite" in its name, as well a not-working linebreak for the elite boyar.

Expansion support (if this mod is wrongly played on expansions dataset): Added a more detailed description of the Feitoria in the civ bonus overview.
