[Cooker] Wiki reorganisation for packaging stuff

[Guillaume Rousse]

I've spent some times reorganising Wiki's content related to packaging, 
with the following intents:

- better content distribution
90% of original content is still located in old monolithic rpm howto, 
making finding information uneasy. Distributing the information in more 
smaller parts should help locate pertinent information quicker.

- separation of concern
Building a package is a different issue than uploading it on the 
cluster. Keeping them separated will help different audience to find the 
information that is relevant to them.

- redudancy diminution
Informations about various tools were dispatched in many places. Using 
some topic-based organisation, such as all tools togethers, help reduce 
redundancy and incoherencies.

Of course, this works led me to make some discussable choices. For 
instance, I preferred to group all potential errors in one single page, 
including rpmlint errors that had their own page before. My reasoning 
was that beginners usually have trouble guessing what is causing the 
error, and they should have the answers directly, instead of first 
guessing where to look for it. I know rpmlint is usually easy to figure, 
but let think at autotools...

As always, comments welcome.

John, I found quite common inconsistencies between the pages, such as 
the heading level used for the title, the depth of the TOC, the use of 
parenthesis for changelog, etc... Isn't it time for a WikiGuideline too
