Quoted color bug

[Jacob Ilsų Christensen <firelake mail1 stofanet dk>]

Hi.

I discovered a bug (newest CVS) related to the coloring of quoted messages.
In balsa-app.h MAX_QUOTED_COLOR is defined to be 4. An array,
balsa_app.quoted_color, with 4 entries is then used to hold the quote
colors. In the preferences when changing quote colors, entry 0 and max-1
(i.e. 3) are changed. But when showing colors in a message entry 0 and 1
are used. A quick fix would be just to redefine MAX_QUOTED_COLOR to 2. But
the preferences should probably have an option to define the number of
quote colors as well as dynamically updating the number of color pick
buttons.

Best regards,
Jacob Ilsų.
