VID-2038 Add bucky profiling to User Profile

Add profiling to UserProfile.js. Specifically this is now profiling the opening of the user edit lightbox, a save after a user changes their information, and when a user uploads a new avatar from their computer. Additionally there was a small css change to change the cursor on sample avatars, and I renamed a couple methods to use more accurate names.

Should probably have a stop on 191 as well
