Spent more time with MSBuild and WIX.

Had to use MSBuild Extension Pack to update XML files (which was better than using regex replace). Use WIX to create .msi installation files for the software we create. Would be nice if MSBuild could create these installation packages, but another DSL is apparently necessary. Either way, quite a productive day so far.

Also got Emacs operating smoothly on Windows 7, the 24.5 version was lagging too much but 24.4 seems to be spinning rapdily along.
