gnome-terminal misreads a fediverse identifier as an email

[themusicgod1]

On the fediverse ( the free software social media network of networks - https://jointhefedi.com/ ) the identifier format is

@username@hostname

unlike email which is

username@hostname

What happens:

if you have a fediverse user displayed in your terminal, gnome-terminal deduces that it is an email and if you right click it, you are given the option to 'Copy Mail Address' and 'Send Mail To' instead of just 'Copy'

What should happen:

You should, instead, be given the option to 'Copy Fedi Address' (and, better yet, optionally 'Send DM To') instead of just 'Copy'. Possibly including the 'Copy Mail Address', for backwards compatibility

this doesn't work, though i'm not sure why. it's mostly what I'm going for though

So this patch actually *does* kind of work but only on the gnome-terminal level (and includes some shotgun debugging). Something deeper needs to happen in order to actually make this work - ie bringing up a fediverse client of some kind or a web browser if that's not available.

[themusicgod1 (themusicgod1)]

this patch works a little better, but still needs a fediverse client to capture the 'send toot' case
