Puppet 4 and Hiera 5 compatibility

Updates the puppet-homebrew module to support Puppet 4 and Hiera 5.

This is a breaking change and will not work on older installations.

Deprecate `BoxenBottles` and Homebrew hooks

• Removes support for BoxenBottles and Homebrew hooks
• Updates CI configuration

Update to homebrew 1.0.0

• Changed min_revision of homebrew 1.0.0 (#97)

2.0.2: Merge pull request #93 from salimane/brew_update

• Further Homebrew split fixes.

2.0.1: Merge pull request #92 from jacobbednarz/roll-back-to-working-min-ver…

• Fix Homebrew after the Homebrew/brew and Homebrew/homebrew-core repository separation

2.0.0: Merge pull request #86 from boxen/default-paths

• Boxen's Homebrew defaults to /usr/local (the default) unless you have an existing install in the previous location.

1.13.0: Merge pull request #85 from boxen/fix-downgrades

• Allows Boxen to downgrade Homebrew versions. Previously it just tried to use brew boxen-upgrade and this would always fail if the user had installed a version from Homebrew newer than the version from Boxen. Instead just brew unlink the undesired (newer) version and brew install the desired (older) version.

1.12.1: Merge pull request #84 from boxen/homebrew-revision-bump

• Updates the minimum version of Homebrew which fixes various issues around accidental upgrade of Homebrew packages installed by Boxen

1.12.0: Merge pull request #81 from boxen/binary-tweaks

• use https for binaries
• use new download location. Well, I say "new" but this also means that the bottles from before the base64 encoding was used.
• Don't set C*FLAGS. Homebrew ignores them anyway.
• Don't set HOMEBREW_BUILD_BOTTLE. This stops Homebrew's bottles from ever being used and post_install blocks from being run when Homebrew is run by Boxen. If Boxen maintainers want to build bottles they can/should manually set this variable themselves.

1.11.6: Merge pull request #80 from boxen/create-tap-root

Fix an issue where the Boxen tap root may not be created on fresh installs.
