linux support :-)

• added linux desktop file indexing (icons not yet loaded)
• added open application support for linux
• added open url / google support for linux
• made linux close the application after execution (Keybinds don't work on wayland)
• tweaked url detection to also allow prefixing http(s):// and make it more generic
• use unix sockets on linux to reshow the gui when launching it a second time (keybinds don't work) --cphist show's the clipboard history even tho that doesn't seem to work on linux
• tweak ci for linux, windows and macos
