Adding a bunch of code plus the idea configuration files.  Things run without compiler errors, but not too much functionality is there.  I added the ControlsFX library, which is really cool.  It provides many more widgets and dialogs, and has high quality documentation.  The author said that the project is deprecated now because it's been accepted to be included in Java 8u40, which will be released in March 2015.  Currently the code builds and works in IntelliJ, but the way I imported some libraries broke the mvn build.  So I will fix that for the next commit.
