Increase the history state rate limit to 8 FPS.

This somewhat relaxes the limitation, enabling more legitimate use-cases while
still seemingly being low enough to contain abuse. Also, expressing the
limitation in terms of FPS makes the limit less arbitrary. 8 FPS for history
modification comports with other performance and functionality goals (like 60
FPS for graphics).
