[wp-docs] Version specific banners for Codex

[Lorelle VanFossen]

We talked about the different ways to set version-specific areas and 
articles in the Codex. I and others have played around with various 
designs but I keep coming back to clean and simple, simple, simple. The 
key is clarity, easy identification and recognition, and keep the focus 
on the content. As one of the volunteers here said, we need to have 
these be an "attraction not a distraction".

I've set up a test document to explore our options with the simple 
banners that can be turned into templates for use on the Codex at 
http://codex.wordpress.org/User:Lorelle/Version_Banners. I've also 
consolidated the ideas that seemed the most consistent with current 
procedure for identifying different version applications. For the 
banners, we picked the darkest color background found in the 
Administration Panels for each version. This reinforces the default 
colors with the appropriate version.

These may change to accomodate the new look of the forum and codex when 
they "combine" and merge, but for now, what do you think?

We also need to make a decision about using v1.6 or 1.5 (with v or 
without) in the titles and references to denote version.
