Dbconfigadmin

@kalbermattenm : You'll probably kill me for this major revision in one chunk, but could you please review ?
thanks!!!
there is a lot of commented code in admin_functions.py because in a first step I did not yet implement the filtering there
You told your function that its renderer was `json` (in the line just before `def`). So you don't need to define again the response, because it is done implicitly by `@view_config`...

Get rid of line 89, and just `return translations`

Not sure about it... But if you only use simplejson for these dumps, then you will also be able to get rid of `import simplejson`....
