[Proposal] Subversion configuration

[Vincent Massol]

Hi committers,

I propose we adopt the SVN configuration from the Maven project.  
Right now everyone has his own config which is a pain for several  
reasons:

- line encodings are different. For example in Jeremi's commit all  
the lines of XWikiMessageTool were modified even though he only  
touched a few lines.
- expansion of @version $Id: $
- correct mime types

Here's the file I propose to use: http://maven.apache.org/developers/ 
svn-eol-style.txt
This is from http://maven.apache.org/developers/committer- 
environment.html

If everyone agrees, please install it in your .subversion/ directory  
(on unix) and somewhere in your profile under Subversion/ on windows.  
I'll also put it up on xwiki.org

Thanks
-Vincent
