WeightLifter - Vertex Group Tool, bugfix release

Recently I published my first commercial addon on BlenderMarket and I am very pleased with the reactions I got so far. A big thank you to all those people who purchased the addon!

Of course, no serious piece of software is completely without bugs so I updated the addon a few hours ago. Version 20141018 contains a few small bugfixes and removes a limitation that could lead to crashes when assigning random weights to groups of connected vertices on large meshes (Thank you Wybren for reporting this).
