[Owncloud] Coding Guidelines ported

[Bernhard Posselt]

Hi,

I've been working on the documentation lately and ported the old
guidelines to the new system. I've also added a part about JS.

The page is available here:
http://doc.owncloud.com/server/5.0/developer_manual/codingguidelines.html

Does anyone have comments or opinions on this? I know this is a
controversial subject ;)

Could you help to define the CSS recommendations?
