[OPEN-342] Bug with single-click - reproducible in 1.5.1
as posted in the forum at:

Implementation:
Handling 'keyup' event (just ESC key) so event can be created with the next click after ESC is pressed by the user.

Tested the following scenarios (on windows XP):
1)  FF & Chrome -> Create event in basic.html sample after ESC key and with single click.

Noticed the following:
1) In chrome, 'keypress' and 'keydown' events aren't triggered for ESC key, whereas in FF it is triggering.

Conflicts:
	src/calendar/view/AbstractCalendar.js

…rovide a handler on: “eventdblclick” event

Implementation is to recalculate the no of events to display when the month is changed.

Steps to verify:
in the current TestApp example, load the current month view for march 2013 it has all the test events.  Click the < button to go to feb, then resize to make the browser smaller, then click > to go back to march, the + more links should be displayed properly (not hidden).
