Warning indicators for animators when Auto Keying is enabled during transform

Recently on the bf-funboard list, there have been some requests for clearer
indications for animators that autokeying has been enabled when transforming so
that corrective action can be taken sooner if this wasn't expected. This is
especially important in distributed+collaborative environments where multiple
artists may work on a single shot file: someone working on a shot from
another animator may not be aware that autokeying was enabled, thus accidentally
setting a whole bunch of extra keyframes.

In this current incarnation, we display using red (not hardcoded, but using an
existing theme color) a solid 1px border around the 3D view while transforming
with autokeying enabled. In addition to the border, a blinking indicator (record
icon + "Auto Keying On" text) appear in the top right corner, as inspired by the
traditional recording indicator icons on camcorders.
