Keyframing Operators: Improved Error Messages

* Keyframing operators now use the reports system for displaying all its error messages. 
- The benefit of this is that users no longer need to check the console for error messages if keyframing fails.
- Unfortunately, reports are not currently viewable in any space/view in Blender, so...

* Added a temporary operator (UI_OT_reports_to_textblock), which can be accessed in the UI from the button which appears in place of the icon when more than one report exists. This dumps the current list of reports to a textblock "Recent Reports", from which they can be viewed. 

This isn't really nice, but at least we now have a way to view these again, which makes debugging some things a pain.

* Bugfix #24606 - when trying to add keyframes to F-Curves with F-Modifiers already which alter the curve significantly enough that the keyframes will have no effect, there are now warnings which aim to alleviate any confusion.
