Added ability to clone from a local repository to a (new) remote one.
Rearranged the clone command a good bit to make sure it validates that
the source does exist and that the destination doesn't before doing anything.
Before I moved the source repo check it would create the destination
repository before it verified the source existed.
Moved the responsibility for creating the destination repo root directory
entirly into the localrepo class so that local to local cloning doesn't break.
This also simplifies the code a bit since it's no longer being done in both
clone and init.
Changed the names of the 'repo' and 'other' variables to 'dest_repo' and
'src_repo' to maintain my sanity.
Passes 82/83 tests. The only failure is the version number test, which I
suspect is supposed to fail since it comes from a generated file.

#
# this hook allows to allow or deny access to parts of a repo when
# taking incoming changesets.
#
# authorization is against local user name on system where hook is
# run, not committer of original changeset (since that is easy to
# spoof).
#
# acl hook is best to use if you use hgsh to set up restricted shells
# for authenticated users to only push to / pull from. not safe if
# user has interactive shell access, because they can disable hook.
# also not safe if remote users share one local account, because then
# no way to tell remote users apart.
#
# to use, configure acl extension in hgrc like this:
#
# [extensions]
# hgext.acl =
#
# [hooks]
# pretxnchangegroup.acl = python:hgext.acl.hook
#
# [acl]
# sources = serve # check if source of incoming changes in this list
# # ("serve" == ssh or http, "push", "pull", "bundle")
#
# allow and deny lists have subtree pattern (default syntax is glob)
# on left, user names on right. deny list checked before allow list.
#
# [acl.allow]
# # if acl.allow not present, all users allowed by default
# # empty acl.allow = no users allowed
# docs/** = doc_writer
# .hgtags = release_engineer
#
# [acl.deny]
# # if acl.deny not present, no users denied by default
# # empty acl.deny = all users allowed
# glob pattern = user4, user5
# ** = user6
