OSD bg and general border changes

- darker, less transparent OSD
- brighter OSD border
- no border for over view panels and entry
- fix border color of popups
- remove trough variable as osd trough and popup trough cant have the same color if dependant on fg_color, fixed hex could also work
- thinner workspace border
