phpenv 0.2.0

Added

• Added support for phpenv-sh-* commands, which run inside the
  current shell instead of in a child process.
• Added an phpenv shell command for conveniently setting the
  $PHPENV_VERSION environment variable.
• Added support for storing phpenv versions and shims in directories
  other than ~/.phpenv with the $PHPENV_ROOT environment variable.
• Added support for debugging phpenv via set -x when the
  $PHPENV_DEBUG environment variable is set.
• Added support for plugin bundles in ~/.phpenv/plugins as documented
  in issue #102.
• Added /usr/local/etc/phpenv.d to the list of directories searched
  for phpenv hooks.
• Added support for an $PHPENV_DIR environment variable which
  defaults to the current working directory for specifying where phpenv
  searches for local version files.

Changed

• Renamed phpenv set-default to phpenv global and phpenv set-local
  to phpenv local. The set- commands are deprecated and will be
  removed in the next major release.
• phpenv now uses greadlink on Solaris.

Fixed

• Fixed an issue with phpenv rehash when no binaries are present.
• Refactored the autocompletion system so that completions are now
  built-in to each command and shared between bash and Zsh.
