more backend

there isnt any significant change in the frontend but there’s a ton of backend refactoring and bugfixes. performance should be slightly better now with large copy/pastes.

changelog:

• associate IDs with clipboard events so that we only have to pass IDs between the frontend and backend instead of the whole content.
• make paste operation more efficient
• ignore clipboard events caused by Squirrel itself (a bit hacky to achieve this but good enough)
• Quit button in tray icon menu so Squirrel can actually be closed (there was no way to close it before except killing it)
• make the shortcut to bring up Squirrel work in almost all situations
• refactor AppState + some other things
• more cleanup and comments

anyways, attached image is the tentative color palette i might implement. i have no idea how to do this and which colors to use where or if it would even look good so i might just ditch it in the future. we’ll see.

todo

still have to test on linux and load history on app launch. probably will work on that next.
