Spelling errors.

Hi guys,

Yesterday I noticed a few errors in some of the unit cards (stats) and in other things. I'll post them here just in case they'll ever be changed. Of course this isn't game-breaking or anything so I refrained from putting this in bugs.

(Intel is capitalized)

These are just 3 errors I'd seen so far in a 10 minute search yesterday. When I have enough time I'll try to find some more, there is probably more to be found.
