feat: customizable active prefix & highlighting style for wofi

[Alan-Kuan]

I added 2 features.

1. customizable active prefix

   [dmenu]
   active_chars = v  # (default: ==)

2. highlight active connection and customizable style for wofi I don't use other menus, and don't know whether it's possible there, so I only support wofi.

Warning There's a breaking change. I renamed rofi_highlight to highlight. In my opinion, it's better than introducing another wofi_highlight field.

[dmenu]
highlight = True

Default highlighting style is bold text.

The followings are fields for the highlighting style.

[dmenu]
highlight_fg = #f2b468
highlight_bg = black
highlight_bold = False

Please tell me what to do if I missed something. Thank you!
