Syntax highlighting for GtkSourceView (GNOME Builder, gedit)

[Grey Nicholson]

Hi folks!

I've been using text/gemini for notes recently, because it's suitably 
simple and easy to parse.

I made a language spec for gedit, which I thought other people might 
find useful; you can find it at:
=> 
https://git.scuttlebot.io/%25bIpwmyP44M5EXF6SdICYQa8rBHhvRRtmqnclkZRx2%2BE%3D.sha256

It also works in GNOME Builder, and theoretically any other text editor 
using GtkSourceView versions 2 to 4.

Cheers,
