Add Git button to Discord RP

[DryByte]

This adds a button to the rich presence for opening up the current repository URL. It reads the config and get the url from the remote origin, if none is found it will not display the button.

Added two new options to the settings:

// Show button for opening git repository on browser
"git_repository_button": false,

// Default message for git repository button (supports format)
"git_repository_message": "Git Repository",

The config parser is a bit rudimentary but it'll get the job done in case it is needed.

LGTM (though untested because I don't actually use this package).

This flag was added in Python 3.7 and the default plugin host in ST uses 3.3, so it will never work.

You'll need to either use the workaround that is also in place in Default/exec.py to set the options directly (for Windows only) or tell ST to use the 3.8 host by adding a .python-version file in the package root with the contents 3.8, which will also break compatibility with ST <4.

Edit: Actually, ST3 will just try to execute the package with its 3.3 host and run into the exception on this code, causing the fallback config parser to be used, so I guess it would actually be fine to just do that. It obviously needs to be tested whether the package works fine under 3.8 first, though.

Ah whoops, I'll change it to use STARTUPINFO for Windows for the popen options, would that work for v3.3 and versions?

[FichteFoll]

Yeah, that should work for all versions (even ST2 😉).
