[kde-doc-english]Errors in kdegames/kbattleship's documentation

[Eric Bischoff]

Dear proofreaders,

horizotally
=> should be "horizontally"

At the time of writing, &kbattleship; requires &kde; 3.x or greater and &Qt; 
3.x or greater.
=> either replace 3.x with 3.0 (twice), either remove "or greater"

I could have fixed the first one by myself, but for the second one, I prefer 
to let you do it.

Thanks in advance.
