Coding conventions

[Vincent Massol]

It would be cool if all committers used the coding conventions have  
defined and agreed upon. There are Eclipse and IDEA configuration  
files for them here: http://www.xwiki.org/xwiki/bin/view/Community/ 
CodeStyle

Generally speaking all committers should read everything that's on  
http://www.xwiki.org/xwiki/bin/view/Community/

Feedback is welcome BTW but unless someone says something this is  
what we've agreed on previously and what should be used.

Thanks
