Date Picker

I just added a date picker to the snippet section.   One limitation of the IDEAScript dialog is that there is no date picker.  I had recently seen a comment on the IDEA forum that they had a script for one but for whatever reason had not posted it in their script section.  So I decided to try and create one of my own.  I think the final product is not bad:

The code has an example of how to use it and access the dialog.  The < and > will move you through the months.  The year drop-down allows you to move in increments of 5 years forward and 5 years back.
