Move common time shifting code to ui/time_shift.[ch]. Change the

shifting routines to return an error message on failure or NULL on
success.  Prettify and simplify the layout of the GTK+ time shift
dialog. Make the cancel button work as expected.

Add a time shift dialog to the Qt port. I used a Mad Lib (sentence)
layout. Hopefully that won't make translation too difficult.  For some
reason time shifts aren't immediately shown in the packet detail. This
appears to be a bug in the packet list / packet detail code.

Add warning role color definitions to tango_colors.h and use them.
