Created WindowFrames class and moved data from PWM and WS

Moved frame data from PWM and WS into the WindowFrames class. Created a
WindowFrames object in both PWM and WS and converted usages of window
frame info to get data from the WindowFrames instance.

Data between PWM and WS is still separate and copied over when
requested.
