File hashes when selecting files

XPatcher 2.2

A small updated with a little feature

Now when you select a file in the Documents tab, it will show SHA1, MD5, and CRC32 hashes of the selected file. closing #5 other changes might be adding .vcdiff to the recognized patch formats (XDelta) but so far it seems kinda broken as stated in #6 .
