Subject: [PATCH] Replace coord font control for ICS font control

In the Fonts the control to set the coord font is removed, as the Cairo
version currently ignores the -coordFont setting. Instead a control to
set the font in the ICS Console is added. As the fonts there are controlled
by tags, and would ignoe the global font setting of the widget, the font
tag is redefined through a kludgy call of AppendColorized with a NULL
string as text. This is now interpreted as a signalfor recreating the font
tag based on the current icsFont, which will then only be applied to
future messages.
