- Without this, vale won't correctly detect where the styles are.

This is the newest version that works with Ruby 2.3.

Also, update the `.gitignore` to hide it while we're here.

This allows maintaining more settings in one place.

This is a clearer branding for us to use.

Also, as part of testing this, make some fixes to Jekyll in the docs folder.

Fixes #5835

Exclude subdirectories and specific files. This makes adding/removing files on newly vendored versions much easier.

We aren't going to vendor its dependencies because we already require
a systemwide installation of `rubocop` to work in your editor. This
avoids requiring users to manually do another
`gem install rubocop-rspec` to have their editor integration behave as
expected.

Rather than having to manually keep track of what version each thing in
here is and copy files around by hand on update let's use Bundler's
standalone mode and careful use of `.gitignore` to help us do it.

This means a `bundle update --standalone` will allow us to update all
gems in vendor.

We could consider vendoring other gems this way in future but I'd
suggest only doing this for gems with no dependencies or at least gems
with no native extensions. The only gem this applies to that we
currently use is `ruby-prof` and I'm not convinced it's widely used
enough to warrant vendoring for everyone. Perhaps that's another
criteria: it should be functionality that's used by non-developer
commands and/or normal Homebrew usage.

Remove a bunch of unneeded, old directories and generally cleanup.

- Ignore files that are generated by `brew tests`
- Make the SVN tests work without prompting for GitHub's SSL certificate

- check in the Gemfile.lock
- use a modern Ruby version
- remove gem upper limits

also, unignore it.

This reverts commit 3e4547f5, reversing
changes made to 6edf9382.

Homebrew's actually ended up using a fair few gems. While we want to
avoid Bundler at runtime (and this PR still does that, in fact uses
Bundler even less at runtime than it did before) writing our own version
to use at build-time seems redundant.

Import new brew.sh CSS changes to improve the appearance of tables and
links.

This smooths over the transition for users who have an existing
bundle config in this location due to having gems installed at the old
path.

Closes #2203.

GitHub now nicely generates a documentation site for us at
http://brew.sh/brew based on our docs folder. Optimise the output of
this and the GitHub docs directory for readability and the various user
groupings.

This fixes the ignoring in libgit2 clients that don't read nested
`.gitignore` files.

Also, check in this manpage, adjust the Rakefile and remove the old one.

Fixes #731.

The vendor Ruby will be put inside `Library/Homebrew/vendor/portable-ruby/<version>`,
with a symlink `Library/Homebrew/vendor/portable-ruby/current` pointed to it.

In addition, a `Library/Homebrew/vendor/portable-ruby-version` will
track the latest version of vendor binaries.

This gives us version control on vendor Ruby and enables us to bump vendor
Ruby whenever needed such as security update.

Since #292, HOMEBREW_CACHE was moved to a per-user directory. This makes
it unsuitable to store global lock files on multiple users environment.

Therefore, introducing a global lock directory `/Library/Lock.d` to
store lock files from formula lockers as well as `brew update`.
