1.8.4.2

• p and P in map navigates jump history
• C in map centers view to current cursor position
• Disable autocommands during panning -- should speed up panning and cause less conflicts with other plugins
• Simplify help
• Separate prompt for hotkey label autotext (useful for custom regex labels)
• Scrollwheel down in map wasn't checking bounds
• Reference splits in plane by (possibly unloaded) buffer number rather than path
• Adjacent duplicate splits in plane now ok
• Inline a few functions
• Mouse speed wasn't applying to out-of-plane vertical panning
• Minor optimizations
