Remove git-zip-tree

git-zip-tree can be safely removed because it was never part of a formal
release.  This patch makes 'git-archive --format=zip' the one and only git
ZIP file creation command.

-NAME
-----
-git-zip-tree - Creates a ZIP archive of the files in the named tree
-
-
-SYNOPSIS
---------
-'git-zip-tree' [-0|...|-9] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-Creates a ZIP archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated ZIP archive.
-
-git-zip-tree behaves differently when given a tree ID versus when given
-a commit ID or tag ID.  In the first case the current time is used as
-modification time of each file in the archive.  In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored as an archive comment.
-
-Currently git-zip-tree can handle only files and directories, symbolic
-links are not supported.
-
-OPTIONS
--------
-
--0::
-	Store the files instead of deflating them.
-
--9::
-	Highest and slowest compression level.  You can specify any
-	number from 1 to 9 to adjust compression speed and ratio.
-
-<tree-ish>::
-	The tree or commit to produce ZIP archive for.  If it is
-	the object name of a commit object.
-
-<base>::
-	Leading path to the files in the resulting ZIP archive.
-
-EXAMPLES
---------
-git zip-tree v1.4.0 git-1.4.0 >git-1.4.0.zip::
-
-	Create a ZIP file for v1.4.0 release.
-
-git zip-tree HEAD:Documentation/ git-docs >docs.zip::
-
-	Put everything in the current head's Documentation/ directory
-	into 'docs.zip', with the prefix 'git-docs/'.
