7c51e23d25 GB: Fixed envelopes being clocked when period is 0 
Based on Megaman 2 and Taiyou no Yuusha the envelopes shouldn't be ticking when period is set to 0 (otherwise the sound in these games breaks - especially the noise channel)
This seems to contradict old documentation that says a period of 0 is treated as a period of 8, but test roms don't seem to validate either behavior and this fixes the audio for both games.

2f3ccc92c3 PCE: Fixed CPU bug that caused memory flag to not be restored properly by RTI 
If any IRQ occured immediately after SET, returning from the IRQ would have the memory flag cleared, which caused the next instruction to behave completely differently from what was intended.
This caused issues in Ankoku Densetsu because it uses SET a lot and has the timer IRQ running constantly

01c65c3549 PCE: Fixed shaking in Final Soldier & Jackie Chan 
Both games do CLI followed by LDA $0000 in their IRQ handler. The old logic would prevent an additional IRQ from firing after the LDA, because the LDA acknowledges the IRQ.  But at this point, the CPU already processed the IRQ and will execute it anyway (the acknowledge is too late because it occurs on the last cycle of the instruction).  Both games rely on this behavior, otherwise the IRQ handler's logic is executed too fast and the shaking occurs depending on the timing of the timer irq vs the rcr irq

SNES: Add SNES Accurate Mouse Movement (#15) 
This code approximates a real SNES mouse and has a bool for a non-existent UI option for SNES Mouse Accuracy Mode.
It also lets the mouse move 1 pixel despite sensitivity settings in Mesen classic behavior.
