add 'Name' column to 'EC2 Instances' view
ignore eclipse-generated folders that shouldn't be commited
factor out instance view column logic into objects in preparation for custom columns
add menu, menu item, and dialog to instances view where user can specify tag columns to display
temporarily defend against an NPE I don't understand yet :)
defend against an NPE resulting from the new configure tag columns menu
fix broken sorting; reset instance comparator after accepting new tag column configuration
allow user to specify which built-in columns to display in the instance view
support copying more instance properties to the clipboard
Change 'Configure Columns' menu entry to be a simple push-button (as apposed to a radio with a check)

MenuAction and supporting/surrounding classes are meant to handle menus with mutually-exclusive menu items (like a group of radio buttons). I'm cheating here by using that API to expose a configure columns menu action, which has no state (at least as far as the menu is concerned)
do nothing if configure columns dialog is canceled
improve UI/presentation for configure columns menu and dialog
pre-populate configure columns dialog with current column state
cleanup code
Merge branch 'ec2_instance_name' - implement configurable columns for ec2 instance view
