Changed the hiscore plugin to save inside the "hiscore" folder in the
plugin data directory. The old hiscore path setting has already been
removed from MAME for some time. This means the plugin was always
saving in the "hi" folder in the working directory with no way to change
it, which is problematic on Linux and macOS, particularly for distro
packagers. There are lots of plugin and UI changes in this release, so
we may as well get this out of the way now. Also made it possible to
change the "timed save" option from the Plugin Options menu, and save
that in the data folder, too.
Documented the input macro plugin. The only undocumented plugins now
are the cheat plugin, the cheat finder plugin, and the port name plugin.
* Also added a couple of missing command-line options, and added a local
table of contents to the (rather long) command line options page.
-Added a separate CI target for localisation updates that produces an
artefact, and removed the message catalogs from the trigger paths for
the Linux CI build.
