egit (eclipse plugin) now knows how to make commits

Egit, the eclipse git plugin now has the ability to make commits. 99%  
of the credit belongs to spearce and robin, as most of my work has  
been on hooking it into the GUI.

Please note that at this point any commits made will have a fake name/ 
email, because we don't read the git config files at present. Also,  
this is not extensively tested, but appears to work with what I've  
used it on so far. Currently, it will only commit changes that are  
already in the index.
