1.15: Features To Handle Reported Edge Cases

This release is a bulk fix for the majority of edge-cases reported on the issues page.

Added: #34 - measure_from: Release as an option settable in the config to measure chatter delay from the last key release instead of the normal behavior of measuring from the last key press. Hotkeys register to the windows hotkey system, so they shouldn't conflict with anticheats and the like in the way that the main keyboard interceptor sometimes does.
Added: #30 - ability to register hotkeys to enable, disable, or toggle whether the blocker is active.
Added: #30 - tempdisable and tempenable hotkeys to also allow a form of disabling that's compatible with AutoHotKey scripts and similar in a clean way.
Added: #28 - there is now duplicate process detection that will give you a choice as to what to do when the app launches when another instance is already running.
Added: #32 - you can now add a sound file as chatter.wav in the same folder as the program's .exe file and it will be played when chatter is detected. No audio systems are loaded if you don't use this.
Added: hotkey_tempblock allows you to temporarily block all input, useful in particular for silencing releases of keys if you want apps to think the key remains held down.
Fixed: #31 - the program broke when trying to enable automatic startup if you somehow lacked a startup folder entirely.
