Bugfixes

Hi! I saw this at ICLS and think it is neat. I do some javascript stuff from time to time. Fixed a couple of bugs I noticed where uploaded artifacts went beyond the bounds of the timepoint, and users could only enter one character at a time into the note textarea. Not sure if the reloadAllNodes would hurt anything else, didn't seem to hurt saving etc. when I commented out. Happy to keep playing around when I have time if it's helpful.
