Document git-gui, git-citool as mainporcelain manual pages

Jakub Narebski pointed out that the git-gui blame viewer is not a
widely known feature, but is incredibly useful.  Part of the issue
is advertising.  Up until now we haven't even referenced git-gui from
within the core Git manual pages, mostly because I just wasn't sure
how I wanted to supply git-gui documentation to end-users, or how
that documentation should integrate with the core Git documentation.

Based upon Jakub's comment that many users may not even know that
the gui is available in a stock Git distribution I'm offering up
two basic manual pages: git-citool and git-gui.  These should offer
enough of a starting point for users to identify that the gui exists,
and how to start it.  Future releases of git-gui may contain their
own documentation system available from within a running git-gui.
But not today.

+NAME
+----
+git-citool - Graphical alternative to git-commit
+
+SYNOPSIS
+--------
+'git citool'
+
+DESCRIPTION
+-----------
+A Tcl/Tk based graphical interface to review modified files, stage
+them into the index, enter a commit message and record the new
+commit onto the current branch.  This interface is an alternative
+to the less interactive gitlink:git-commit[1] program.
+
+git-citool is actually a standard alias for 'git gui citool'.
+See gitlink:git-gui[1] for more details.

+git-gui(1)
+==========
+
+NAME
+----
+git-gui - A portable graphical interface to Git
+
+SYNOPSIS
+--------
+'git gui' [<command>] [arguments]
+
+DESCRIPTION
+-----------
+A Tcl/Tk based graphical user interface to Git.  git-gui focuses
+on allowing users to make changes to their repository by making
+new commits, amending existing ones, creating branches, performing
+local merges, and fetching/pushing to remote repositories.
+
+Unlike gitlink:gitk[1], git-gui focuses on commit generation
+and single file annotation, and does not show project history.
+It does however supply menu actions to start a gitk session from
+within git-gui.
+
+git-gui is known to work on all popular UNIX systems, Mac OS X,
+and Windows (under both Cygwin and MSYS).  To the extent possible
+OS specific user interface guidelines are followed, making git-gui
+a fairly native interface for users.
+
+COMMANDS
+--------
+blame::
+	Start a blame viewer on the specified file on the given
+	version (or working directory if not specified).
+
+browser::
+	Start a tree browser showing all files in the specified
+	commit (or 'HEAD' by default).	Files selected through the
+	browser are opened in the blame viewer.
+
+citool::
+	Start git-gui and arrange to make exactly one commit before
+	exiting and returning to the shell.  The interface is limited
+	to only commit actions, slightly reducing the application's
+	startup time and simplifying the menubar.
+
+version::
+	Display the currently running version of git-gui.
+
+
+Examples
+--------
+git gui blame Makefile::
+
+	Show the contents of the file 'Makefile' in the current
+	working directory, and provide annotations for both the
+	original author of each line, and who moved the line to its
+	current location.  The uncommitted file is annotated, and
+	uncommitted changes (if any) are explicitly attributed to
+	'Not Yet Committed'.
+
+git gui blame v0.99.8 Makefile::
+
+	Show the contents of 'Makefile' in revision 'v0.99.8'
+	and provide annotations for each line.	Unlike the above
+	example the file is read from the object database and not
+	the working directory.
+
+git gui citool::
+
+	Make one commit and return to the shell when it is complete.
+
+git citool::
+
+	Same as 'git gui citool' (above).
+
+git gui browser maint::
+
+	Show a browser for the tree of the 'maint' branch.  Files
+	selected in the browser can be viewed with the internal
+	blame viewer.
+
+See Also
+--------
+'gitk(1)'::
+	The git repository browser.  Shows branches, commit history
+	and file differences.  gitk is the utility started by
+	git-gui's Repository Visualize actions.
+
+Other
+-----
+git-gui is actually maintained as an independent project, but stable
+versions are distributed as part of the Git suite for the convience
+of end users.
+
+A git-gui development repository can be obtained from:
+
+  git clone git://repo.or.cz/git-gui.git
+
+or
+
+  git clone http://repo.or.cz/r/git-gui.git
+
+or browsed online at http://repo.or.cz/w/git-gui.git/[].
