Fixes #897 with amendment

The Meta Programming System is a language workbench created by JetBrains.

http://jetbrains.com/mps/

By default this file will ignore the generated java source and the compiled java classes that are
produced by the language compiler. It will only add the Models which contain all information
necessary to reproduce the the java source code and the the resulting class files.

In addition to the generated source code it will ignore the test result files and test property files,
because those are also generated from the models.

The ignore file also prevents commiting the workspace.xml which contains the currently editor state,
like open files and cursor position.

I made some changes to the original pull request to remove complexity which
I believe was not needed.

From the discussion on #1013:

Since the rule in VS is packages/*, the fact that it contains a slash means
that it is anchored to the top level. That is, is will only apply to
a directory called packages at the top level, and not to any at deeper
directories like App_Data. So these rules at the bottom of your changes
actually aren't necessary after all. I just confirmed this with a quick test.
