a bunch of backend improvements:

• store timestamps for copy events
• more efficient message passing between frontend and backend
• Clear History functionality
• system tray (!) (pls ignore the missing icon in the tray, we don’t have an icon for the app yet)
• slightly better UI

on the topic of UI, i’m getting around to deciding a color palette for the app. i will probably work more on the UI for a bit before switching gears to add more functionality (like image support). if i decide i want to ship early, v0.1 will probably go without image support and just get a lot of polish with text only functionality.
