Reworked the non-blocking reports display in the info header:

* Now it displays the last report from the global list, not just from operators
* Rather than disappearing when a new operator is run, it stays until it times 
out or a new report is added
* Fun animated transitions ;)

Now need to investigate report usage with popups. Ideally we can have most
 reports non-blocking, so they're less intrusive, only popping up for dire errors.
Problem is many things in Blender right now are marked as RPT_ERROR 
when probably RPT_WARNING is more appropriate. Should probably keep 
RPT_ERROR for things that demand immediate attention.
