[Slight suggestion] Improve readability of comic status on favorites page

[Olf0]

Originally filed as tardypad#59.

The status of a comic strip is currently displayed with a black foreground over a background coloured with a darker version of the comic colour. In some cases this results in a very poor contrast between the the darkened background colour and black.

An idea to solve that à priori:

• Allow for an extra field named titleColor in a comic's info.json, which contains the colour for the title of the comic on its cover.
• Also use this titleColor as the foreground colour of the status icon and text (still over a darkened background colour).

This way the titleColor and the background colour of covers can always be chosen to provide a stark contrast between each other.

Comment by olf: I am not sure that this effort is worth it to address this minor issue.
