[PATCH v2 1/6] gitk: set intitial colors of swatches using the available helper

["Johannes Sixt via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Sixt <j6t@kdbg.org>

After the user has selected a color in the Preferences dialog, the
helper proc prefspage_set_colorswatches is used to update the colors
shown in the Preferences dialog. Use this proc also to show the initial
colors after the Preferences dialog is constructed. This keeps the
procedure that gives the UI elements their colors in a single place.
