NetBeans formatter for mx projects

[Jaroslav Tulach]

Dear NetBeans IDE users,
since today you can instruct your favorite IDE to format sources on save in 
the exact format requested by your mx configuration. Following steps are
needed:

1. get the most recent mx - e.g. call `mx update`
2. regenerate IDE projects - e.g. call `mx netbeansinit`
3. install the formatter module into your IDE: http://plugins.netbeans.org/
plugin/50877/eclipse-code-formatter-for-java-eclipse-mars-4-5

That is all. Once you save a file, it shall be properly reformatted thanks to 
https://github.com/graalvm/mx/commit/fb045df21796d36dc57fcd04f24773d2c4cce967
and hard work of Benno.

Enjoy and send many thanks to Benno who created the formatter module.
