Umh, there are a few bugs in there, sorry :p
I'll have to release b1r6_2 soon, so this is actually playable.
Please note that this release is more like a test, the cvars aren't definite (the power meter goes from 0.5 to 1.5 times the original speed, I plan to make it something like 0.2 to 1.1 or 1.2)
