Add SSH Key validation. It should start from 'ssh-rsa ' or 'ssh-dss'

Beyond the way it starts, we can probably ensure the content is valid as well. What characters are legal in a key? Mine only has A-Za-z0-9\/=, plus @ for the comment at the end.

I think its enough simple validation like 5afb16e4. The main goal is to prevent gitolite error. dont care about if it really valid :)

had really nasty problems related to this one few days ago

basically there was a mistake and this ssh key was uploaded:

hostname$ cat key.pub
ssh-rsa ...

which passed the validation but crippled gitolite completely to the point where i had to manually check out gitolite admin repo and remove corrupt key by hand and then cleanup the gitlab database

not a pleasant experience :)
