Add option to hide menu bar icon

[CollinsVakayil]

For those of us that use the shortcut to trigger Yippy clipboard, we'd like an option to hide the menu bar icon. Also please add a button to clear clipboard history when the clipboard window is open.

Yes please! The functionality of Yippy is amazing, but it serves little purposing taking up menu bar icon space. Thank you so much to the developers!
