Wiki documentation fixes

[brettle]

I read through the entire wiki (except the API docs) today and figured that while I was at it I'd correct the various spelling and grammar errors and make a few minor changes to improve readability. A patch (against e8f6e2e) containing my fixes can be found at:

https://gist.github.com/brettle/10007085

You can download the raw patch at:

Too bad this issue was overlooked for so long, now that the wiki is hosted on OpenProject with a new syntax it will be harder to apply this patch... I'll see what can be done (ping @StraToN and @TheoXD too).

Still interesting. I'll import this file locally and re modify it for the new Open Project wiki. And without forgetting giving credit to @brettle. Thanks to him

@her001 @StraToN If one of you has some time to check this patch and see what parts would still be relevant in the new documentation, that would be great! :)

Noted, added to my todo list. I wouldn't mind if someone else beat me to it.
