Added a formula for installing mvnvm, the Maven Version Manager
version, hash, test, comments

* used today tar.gz,
* updated hash,
* changed test to copy the maven one + mvnvm.properties
* removed comments
using tar.gz instead of zip
remove empty line and use double quotes everywhere
depends on java!
version 0.1, removed java dependency
correct java dependency, more double quotes
mvnvm: add 0.1 bottle.
