"Poses" button changed to "Pose"

There is a "Unpose" button and there should be a "Pose" button to
match - there used to be, but got changed. There's no other "Pose"
button, so... done.
Extraneous "x" - waste of space.

Extra "x" lying around... yes, it's minimal - YES, it's a
one character commit - YES, I DID IT! So shoot me :P
