DeleteDiscordMessages Versions Save

Implemented a version with does not use a Popup window, but instead adds button to the discord toolbar that opens a popover/sidebar inside the discord UI.

This has a few advantages being it should fix issues with popups being blocked #71 #70 #45

Solves the requests for bookmarklets #22 #19 because it is compatible with user scripts, so you can install it with Tampermonkey and have it permanently there.

It is possible to run it from the Electron app and not only inside the web app #68.

It should reduce memory usage by not creating another windows with another document.
