[sldev] CMake project merged to release branch!

[Bryan O'Sullivan]

I'm pleased to announce that our release (aka "trunk") branch is now 
built using CMake on all platforms.

This should have a number of benefits for the developer community:

One source of all build information, for every platform.
On Windows, upport for Visual Studio 2005 and 2008.
Easier to develop and maintain patches.

For docs, see here:

I've made a quick pass over developer info for other wiki pages, but 
please feel welcome to edit and update those pages as appropriate.  I've 
been editing wiki pages all afternoon, and my brain has melted.
