Replace Xmobar with Polybar

- Remove unneeded imports
- Move global tangle path to individual code blocks
- Add docks hook to avoid polybar when tiling
- Add dwm-style workspace cycling
- Fix keybindings to put ctrl before shift
- Reset window sizes when force re-tiling
- Add ewmhDesktopsEventHook to myEventHook for polybar integration
- Launch polybar instead of xmobar
- No tangle xmobar config and delete it
- Add polybar config from dwm with bunch of tweaks
