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.
This commit adds a new Wallpaper configuration option to the
WorkspaceConfig, allowing the user to specify a path to a wallpaper
image file, and to specify whether to generate a base16 palette from the
colours of that image file.
Theme generation is enabled by default when a wallpaper is selected.
A set of theme options can be given to customize the colours of various
borders and accents.
The themes generated are also plumbed through to the komorebi-bar.
The palette generation algorithm from "flavours" (which has been forked
and updated) is quite slow, so the outputs are cached to file in
DATA_DIR, and keyed by ThemeVariant (Light or Dark).
The Win32 COM API to set the desktop wallpaper is also quite slow,
however this calls is async so it doesn't block komorebi's main thread.
