tools: Add arrow keys to Shear tool

Browse source 
Per user request, this allows you to use
arrow keys to adjust the shear tool.
Left/right move the shear on the X axis,
up/down move the shear on the Y axis.
By default, it moves one pixel at a time.
If you hold shift (similar to the move
tool), it moves based on the slider's
page increment setting (factoring in the
current zoom).
