Assorted Bugfixes:
* Adding new Keying Set paths didn't initialise the id-type setting. Make this default to Object
* Fixed bad poll callbacks for Graph Editor operators working on keyframes, which were expecting F-Curves to be selected too to be eligible for editing. This was often too restrictive, resulting in nothing happening.
* Fixed error with default property for Debug Redraw-Timer Operator not being set. However, this operator is currently still no use, since the info popups are now disabled.
