[PATCH 00/13] gitk: tweak rendering of remote-tracking references

This patch series changes a bunch of details about how remote-tracking references are rendered in the commit list of gitk:

* Omit the "remote/" prefix on normal remote-tracking references. They
  are already distinguished via their two-tone rendering and (usually)
  longer names, and this change saves a lot of visual clutter and
  horizontal space.

* Render remote-tracking references that have more than the usual
  three slashes like

      origin/foo/bar
      ^^^^^^^

  rather than

      origin/foo/bar (formerly remotes/origin/foo/bar)
      ^^^^^^^^^^^              ^^^^^^^^^^^^^^^^^^^

  , where the indicated part is the prefix that is rendered in a
  different color. Usually, such a reference represents a remote
  branch that contains a slash in its name, so the new split more
  accurately portrays the separation between remote name and remote
  branch name.

* Introduce a separate constant to specify the background color used
  for the branch name part of remote-tracking references, to allow it
  to differ from the color used for local branches (which by default
  is bright green).

* Change the default background colors for remote-tracking branches to
  light brown and brown (formerly they were pale orange and bright
  green).

I understand that the colors of pixels on computer screens is an even more emotional topic that that of bikesheds, so I implemented the last change as a separate commit, the last one in the series. Feel free to drop it if you don't want the default color change.

Along the way, I did a bunch of refactoring in the area to make these changes easier, and introduced a constant for the background color of "other" references so that it can also be adjusted by users.

(Unfortunately, these colors can only be adjusted by editing the configuration file. Someday it would be nice to allow them to be configured via the preferences dialog.)

It's been a while since I've written any Tcl code, so I apologize in advance for any howlers :-)

This branch applies against the `master` branch in git://ozlabs.org/~paulus/gitk.
