fix #2281: ctrl + backspace handling in text inputs

[fiddler]

Issue: The InputText component does not handle ctrl + backspace correctly.

Defect: The key combination has no handler setup.

Fix: Added handlers for <C-BS>. Without a selection, it removes the preceding word. When there is a selection it behaves as if just <BS> was pressed and removes the selection.

PS. Went through the contribution guidelines and hopefully got it mostly right here. Comments/improvements welcome! :)

Looks great, @fiddler ! Thanks for thinking through the selection-case and adding the test cases.

Really appreciate the contribution!

Oh, and this would qualify for our license key bounty.

Unfortunately it's not automated yet - but would like to send you a coupon code for it. Are you on twitter or Discord? Can DM you it!

Great that it worked out! No need for a license, I've bought one some time ago so am already good on that front! :)

I have a few more improvements done for handling OSX specific stuff like <D-BS>, <D-a> etc. Do you @bryphe know if someone else is already working on those? I'd love to create a PR for the improvements, but the bulk of work is setting up the tests and don't want to do double work if someone else is already on it.

Thanks for all the support @fiddler ! Sure thing, really appreciate the contribution 😄

This would be great - sounds like it would fix the remainder of issues in #2404 !

Good question, thanks for checking - AFAIK, no one is working on those macOS-specific shortcuts. @fanantoxa is looking at issues with copy/paste, but I don't think it overlaps with the macOS-specific shortcuts.

[fiddler]

Ok, great. I'll comment on the #2404 that I'll be working on it!

[fanantoxa]

@fiddler I got fixed focus management here: #2428
So I'm going to add copy/cut keys now.
I don't have any Mac around (And never had on) so I'd need later some help to make hotkeys work for Mac Os.

Whoops, missed your comment @fanantoxa! Is this still relevant? I can help test/check those. Should be <D-x>, <D-c> `.
