Naming of folder and jar is wrong for ruby-processing and linux

[monkstone]

@fjenett for the library to be picked up on linux (with load_library :guido) the folder name and jar name should be lowercase. Otherwise seems to work OK with latest development version of ruby-processing-2.5.1 (currently noeval branch). You should check out what I've done for drawolver since processing-2.5.0 which was a partial inspiration for my creation of the vecmath library (a replacement for PVector where the norm is to use +, -, /, * as your original extended PVector).

Oh cool, will check out! Thanks!
