ListStyle (compact) replacement for two-column tables

by calling CTable::SetStyle(CTable::ListStyle) one can switch from the
bulky and unreadable-on-narrow-devices-or-nonmonospaced-fonts tables to
a more compact list style of output. The first "column" will be bolded
for better visibility and seperated with a colon from the second.

This is currently designed to replace two column tables only.
