Subject: [dmenu][patch] floatingmenu v1.0 - floating dmenu bar with padding/height/border (extension of floatingstatus for dwm)

NOTE: Added extra flag, '-bo', which allows you to specify the colour of the border explicitly.
By default, the background just inherits the '-sb' flag, to cooperate with default dwm behaviour.

This is my first time patching suckless software. Please feel free to email me if you encounter any issues.
