Repo is out of date with releases

[zrisher]

Hi there,

Looking at your SourceForge release page, there have been three releases of this tool that aren't reflected in this repository's code,

v1.3.8 2014-08-30
v2.0 2015-04-11
v2.1 2015-04-15

@towerofpower256, could you please push the relevant commits? If you like, I could help copy the releases into the repo and create PRs for each version, but I figure you might want to massage it.
