Purged binaries from git history (please re-clone).

I didn't realize quite how much space the binaries were taking
so they have been purged from the repo. They will subsequently
be distributed using github's release mechanism. If you
cloned tt previously you will need to reclone it (it should
save you in excess of 100MB of disk space :P). Apologies
if you are one of the poor souls who tried to 'go get' it.
