Gizmod 3.4 Released!

This is mostly a bug fix release for an issue that cropped up with recent versions of xorg where Gizmod would spike the CPU for long periods of time, however there are a number of other efficiency fixes as well meaning CPU usage has been decreased across the board. In addition to the the fixes come a few new features including:
* Better support for device matching by product and vendor ID codes. If you have one of those hard to identify devices that describes itself with some generic (or empty) device string, this should help.
* initial support for the Logitech Momo racing wheel! Actually currently just the pedals -- you can now use the gas pedal to scroll down, and the brake to scroll up. And, of course, the scrolling speed is dependant on how much you depress the pedals.
* New CMake based build system that should help alleviate some of the compilation issues that revolved around the old autotools based system, specifically with regards to 64 bit supporting library detection.
