Another small patch release.

• Improved: Small optimization - the program already used almost no CPU time to process, but now it uses an even smaller fraction of a millisecond for keystrokes that aren't in your chatter list if you have global threshold set to 0
• Improved: the Stats tab no longer shows any stats about keys that are not in your explicit chatter list if global threshold is set to 0, for privacy reasons
• Documented: The readme now has a section "Perfecting Your Settings" to make it an easy step by step process to get things right
• Documented: the readme now has a table of contents at the top
• Documented: https://github.com/FreneticLLC/KeyboardChatterBlocker/issues/55 - EVkey and possible other keyboard software like it has a minor compatibility issue that can be fixed by adding Packet and Back as keys with a threshold of zero
• Fixed: https://github.com/FreneticLLC/KeyboardChatterBlocker/issues/59 - hide in system tray broke hotkeys.
