Force branch `master` on ⌘\ Lookup

[drewlustro]

Hi.

Thanks for the great plugin!

It would be useful to have a configuration setting to force a particular branch when performing ⌘\ lookups.

In my workflow, I'll be working on a branch that I haven't pushed up to origin yet. I want to see what the code used to look like before my edits, so I invoke GitHubinator and it resolves to my current branch, which not only does not exist (404), but it's not what I'm looking for – I want it to look up the master branch (or whatever).

Of course, the default behavior is proper ✅, but this setting would be quite easy to implement, no?

goes to try...
