This class registers shortcuts and processes key presses. It can also
register multiple shortcuts and shortcuts with multiple keys pressed
sequentially. Perhaps it should also support shortcuts with multiple
keys pressed simultaneously for folks at https://klava.wiki ...
assets.qtpl is no more! Now you can just add files to static/ folder,
make sure the extension is registered in static.go (a shortcoming
that'll be addressed in future Go versions), and you're done! It
searches the local file system first, then falls back to the files
embedded with the binary (in the static/ folder).
See https://mycorrhiza.lesarbr.es/hypha/configuration for an example.
A copy of this example is stored at assets/config.ini.
Use option -config-path to pass the config file. Note that all other
CLI options have been removed. Some of them may be returned later.
Also note that no real testing has been done.
