[TIMOB-18621] Consolidate Java coding standards

We have several different coding standards in use that may or may not differ from our official standards, and are somewhat different from our other languages: https://wiki.appcelerator.org/display/guides2/Java+Coding+Standards Some highlights of cross-language similarity I'd like to achieve: * Tabs * Opening brace on new line, except blocks and flow control * Closing brace on new line (except blocks and flow control, i.e. } else {) * Max line length of 120 (to fit within a normal GitHub review window) A proposed formatting file for Eclipse can be found here: https://github.com/appcelerator/appc-standards/blob/master/languages/java/eclipse-format.xml And below are two examples of what this would change in our code: * Studio: https://github.com/aptana/studio3/pull/297 * Titanium: https://github.com/appcelerator/titanium_mobile/pull/6668
