Fix [mini] config parsing

[czak]

Hey, thanks for a great tool.
I found a small issue in the config parser.

How to reproduce

With this config file the Mini mode does not show anything:

[mini]
handheld_font_size=20
docked_font_size=20
cat_color=#FCCF

(no other entries in the file, just these 4 lines)

Fix

I think it's just a typo in the [mini] parsing block.
With this fix, all modes show up correctly for me.

Yeah, that's correct. Thanks.
