[PATCH 2/3] gitk: do not set fg/bg color scheme for themed Tk

["Christoph Sommer via GitGitGadget" <gitgitgadget@gmail.com>]

From: Christoph Sommer <sommer@cms-labs.org>

Ignore the uicolor preference not just for win32, but also whenever
themed Tk is used. On themed Tk it was frequently only changing the
background of only a few select widgets rather than everything -
and the default uicolor was frequently not the background color that
themed Tk used for its widgets, resulting in a messy looking UI
(mostly light gray, with random widgets surrounded by darker gray borders)
