Support for alternative paste binding

[alternateved]

Hello! Thank you for that package, it works really well from my initial testing. One thing that I've noticed in regards to bindings.

Most applications (browsers, terminal emulators, file managers at least on Linux) support alternative paste binding with Shift+Insert, but in Ghostel that binding results in 2~. Would it be possible to add that binding?

Possible diff:

Alternatively instead of binding C-y we could also just remap yank like so:

Other places where ghostel-yank is used probably would benefit from that as well. What do you think? Or maybe this should be a part of user configuration?

Thanks. I also think that mapping should exist by default. Implemented in main.

Thanks a lot @dakra. I appreciate it!
