Miscellaneous Changes

I made some organizational changes here. Firstly I removed the dependency on JDatePicker (because it's bad and has one of the most convoluted creation processes for such a simple widget) and added a dependency on org.jdesktop.swingx, which has a much easier to use date widget (on which I can just call getDate() and it will give me a Date object. Secondly I changed the TaskEditView to use the new JXDatePicker widget from SwingX, and finally I made one custodial change to build.gradle in the WPISuite directory to match its indent pattern.

You will have to re-run the gradle build after these commits have been pulled, as new dependencies have been introduced to the system.
