[BUG] Unable to manually load Minecraft versions past 1.5.2

[NockTwelve]

Describe the bug Trying to manually load any Minecraft version past 1.5.2 does not work because of a missing launch method "1.6.jar" (even though there is a launch methods folder in the .betacraft\launcher directory). Looking through the betacraft FTP file server storage did not help either, it had .jars in the launch-methods folder, but not 1.6.jar.

To Reproduce Steps to reproduce the behavior:

1. Put any Minecraft version jar past 1.5.2 into the versions folder
2. Select that version and try to load it just like any other version [e.g 1.0]
3. Edit your instance and check "Console Output"
4. See error
