Merge with TAH

manifest hash: 197e0d1a0d7376a9eb72381330462f06490ab821

General:
- Better documentation
- More regression tests
- More specific try/except.
- less code duplication, more code in the right places
- python 2.2 support
- better import support
- export to git
- Code cleanup: apply http://python.org/peps/pep-0008.html

Core:
- difflib creating/removing files (fixed except dates: should be epoch)
- directory foo.d or foo.i with existing file foo (use some quoting?)
- get various options from hgrc (e.g. history always -v, tip always -q)
- better push support (hack exists)
- hg over ssh:// and https:// and rsync://
- hooks for new changesets getting pulled/imported etc.
- make showing removed files (in history etc.) faster.

Commands:
- hg add <directory> should work
- hg status <filename>: file rev, changeset rev, changed, added,
  deleted, sha-1
- select to pull a subset of the heads
- commands.py: number of args too much magic (e.g. in patch())
- automatic pull fallback to old-http://
- optionally only show merges (two parents or parent != changeset-1, etc.)

Web:
- optionally only show merges (two parents or parent != changeset-1, etc.)
- one hgweb with many repos (another script)
- hgweb tip link too verbose
- hgweb: deliver static files (e.g. favicon, stylesheets)
- hgweb personalization: timezone (display/change), display of
  features
- some web servers think hgweb.cgi.[di] is a CGI script with old-http://
  (use quoting (see foo.d in Core) or document server configurations?)
- link children in hgweb
