This commit adds a simple egui helper application which shows a list of
shortcuts defined in a user's whkdrc file. Parsing AHK files is not
supported.
In addition to listing out shortcuts defined in the whkdrc file, the top
line allows users to add filter a filter to narrow down the list of
commands and key bindings to the ones they are interested in.
A new komorebic command "toggle-shortcuts" has been introduced which
will first attempt to kill "komorebi-shortcuts.exe", and then exit if
the kill signal was successful (ie. a process was closed), or proceed to
open "komorebi-shortcuts.exe" if the kill signal was not successful (ie.
no process was closed, so we should open one).
"komorebi-shortcuts.exe" has been added as a floating application in
lib.rs to allow for users to use the "komorebic move" command to
manipulate its position via their existing keyboard bindings.
