Animation Editors: Name-based filtering

I'm finally yielding to months of feature requesting, and adding
support for filtering F-Curves by name, where the "name" here is the
text which is displayed for each F-Curve in the Animation Editor
channel lists.

To use, just enable the magnifying-glass toggle on the DopeSheet
filtering settings, and enter a snippet of text to find within the
names of channels you wish to filter. This is case insensitive, and
currently doesn't support any wildcard/regrex fanciness.

Some examples:
loc <--- location curves only
x loc <--- x location curves only
x eul <--- x rotation curves only
rot <--- rotation curves only
etc.
