ESS 1.1 Released

This is a fairly major update, but the codebase didn't change enough to justify moving to 2.0. Now we have centralized emailing of schedule creations and updates, a WYSIWYG html editor for event notes, lots of bug fixes, and editing of positions that actually work!
Again, if anyone finds any issues, put them into the tracker and I'll push out fixes as fast as school lets me!
