Provide starting-point code formatting templates for eclipse.

The xml file has to be imported into eclipse, but maybe we can use the prefs file directly in .settings for each project.   The formatting doesn't do anything with comments, and running it against develop seemed to regenerate the same format more often than not.

Note that this isn't so much of a pull into MovingBlocks/develop request as it is to make the files available to @msteiger.   Maybe a better way to do this would have been to rebase against his repository?   Still learning the best way to handle things in github, so speak up if I do something wrong.  Especially if you have examples. :)
