Patch, IOStat & Parsing

Friday the 5th of November I first of all got the patch finally working. This wasn't working before, because I was creating a patch while the patched kernel was compiled and the original one was not (this diff resulted in an extremely large patch file).

Afterwards both Sam and I worked on the XenGatherer tool: Sam added the functionality of IOStat so now it is possible to monitor the disk usage of the virtual machines and dom0. I started parsing the ouput files, so our tool generates an output file containing only the required information.
