don't unpause emulator when resetting

[Jamiras]

Fixes an issue where the pause indicator remains on screen when the emulator is reset. Rather than remove the pause indicator, I felt it was more appropriate to not unpause the emulator when resetting. This allows developer to debug memory state as the emulator is reset.

I'm not sure what you mean by "debug memory state", but there could be cores that free the emulated memory and allocate it again while resetting, so it's not advisable to hold pointers to emulated memory while resetting (or when unloading and loading a game).

There are a subset of tickets that occur because a user resets the game and the game doesn't immediately update the memory.

For example, an achievement has a "8-bit 0x1234 = 1 (1)" condition to capture when the player starts something. The hit count will be cleared on reset by the runtime, but if the memory hasn't been updated (even for a single frame), the hit can be captured again before the user gets back to the title screen. Without the ability to framestep through the reset process, that's hard to detect.

We already rebuild the memory map on reset via #209.

Oh nice
