push over http in crew

[Vadim Gelfer]

i have pushed push over http support to crew repo.

default is for push over http to not work.

to enable in safe and secure way, here are steps:

make sure your server works with ssl. push over http default is not to
work over plain http because of risk of password sniffing. (override
with [web]push_ssl in hgrc.)

make http server require client authentication. one way is to put
.htaccess file in same directory as hgweb.cgi or hgwebdir.cgi, with
conctents like this (apache 2.2):

  AuthType Digest
  AuthName "hg"
  AuthUserFile /home/vadim/public_html/.htdigest
  Require valid-user

(digest authentication good because no plaintext passwords sent over wire.)

edit hgrc to have allow_push set:

  [web]
  allow_push = vadim mpm

then you are done.
