Add gtksourceview-3.0 language file

[Philip Withnall]

If we install a gtksourceview-3.0 language file to /usr/share/gtksourceview-3.0/language-specs, gedit and other GtkSourceView?-based editors will get syntax highlighting. This will be particularly useful on the Expo laptop.

I’ve written a language file and will attach it to this ticket. I lack the enthusiasm to get it installed via autotools at the moment though.

The language file follows the documentation here: https://survex.com/docs/manual/datafile.htm. There seem to be some differences between the documentation and common usage wrt *team and *instrument commands. I’ve stuck with what the documentation specifies.

The reference for the GtkSourceView? language-spec format is here: ​https://developer.gnome.org/gtksourceview/stable/lang-reference.html.

You can test the language file by dropping it into ~/.local/share/gtksourceview-3.0/language-specs/.

Thanks. Committed in [506e348a5ef19f8abc3f3a359f7bd927dc54c658] and added the automake runes in [506e348a5ef19f8abc3f3a359f7bd927dc54c658].

Unfortunately CUCC seem to use their own special format (or just free-form text in some cases) for *team and *instrument, and cavern doesn't currently check them so this went unnoticed for ages. Therion's file format implements them pretty much as Survex documents, and it actually checks, so I think CUCC really needs to change to match the documented format.
