Fix vanity-uuid generation "g"s

Thanks to a /u/palordrolap for pointing out the bug, otherwise it would have probably lay dormant for a long time.

Bash scripts for you $PATH

After testing it turns out that arx files are up to x6 slower, even with a simple script like this so I'm distributing the bash scripts "unnixed" in zips. Take care to keep all the files in the same folder or else the script won't work, I would recommend symlinking from your $PATH.

Initial Release

You should be able to to just download vanity-uuid4-arx or vanity-uuid-nospec-arx, chmod u+x and run it. First time running will be slightly slow as it unpacked everything.
