Font/background options for minimised tasks

[chrisjbillington]

This is a fantastic extension, and almost replaces tint2 for me as a bottom panel with a taskbar (separate task lists on separate monitors is the main difference).

One thing I miss compared to tint2 is for minimised windows to be able to have a different font colour/background colour/etc. That way there are three ways to visibly distinguish tasks: currently active, inactive but raised, and minimised.
