Make holding down toolbar buttons slightly less awkward on a high res touch device by increasing the threshold needed to activate a drag.
Fix bug where dragging across the original drag start 'snagged' while the threshold was reactivated.
Bug fix: create link dialog slightly too wide.
Add some validation to the create link dialog. Currently there's no indication to the user that validation has failed other than the fact that the dialog remains in place. Adding an alert screwed up the focus on iOS.
Fixes toolbar display bug on FireFox. Not in a clean way unfortunately...
