Man pages should be the canonical source of hub documentation. People
should use `man help hub` instead of viewing the README, which might not
even correspond to the version they have installed.

This ends the confusing man page build system in which parts of the
README are injected into `hub.1.ronn` source file, deletes the Rakefile
and removes rake from gem bundle.

The examples are deleted because they are now inlined with individual
command documentation. So did the documentation for all hub commands get
deleted from main man page in favor of individual man pages.

However, this makes main man page have absolutely no listing of which
commands are available. This will get addressed as we go forward.

Now `ci-status` consumes the new combined statuses API endpoint designed
for when multiple contexts report statuses independently.

The verbose output is now colorized and is in format where each line is:

    ✔︎<Tab>[CONTEXT]<Tab>[URL]

[ci skip]

Since cloning of private repos over `git:` protocol is not possible,
users were required to manually add the `-p` flag to trigger cloning
over the `ssh:` protocol.

Now, use the GitHub API to obtain information about the repo to be
cloned, and automatically use the `ssh:` protocol if the repo is private
or if the current user has push access to that repo.

Fixes #212, fixes #213

This feature is likely to get dropped from GitHub API in the near
future. The alternative is to simply create a new pull-request and
reference the original issue in the description.

All parameters are optional.

Fixes #290 [ci skip]

Fixes #422, closes #423

Emulates the interface of `git commit`:

  $ hub pull-request -m "This is my title"
  $ hub pull-request -F /path/to/message.txt
  $ hub pull-request -F -

The old way of passing in just title is deprecated

  $ hub pull-request "Deprecated title"

Fixes #183

It doesn't add a remote anymore, as it isn't needed.

It does what GitHub's "Merge pull request" button does:
merges the pull request with a nice commit message that
includes the pull request ID and title. Like `hub checkout`,
it creates a remote, but it does not create a local branch.

Closes #75
