ruby-build 20130129

## Version History

#### 20130129

* Changed `rbenv install` to attempt to install the local app-specific

  version when it is invoked without any arguments.

* Added interactive confirmation to `rbenv install` when the

  destination prefix exists. Pass `-f` or `--force` to force

  installation of versions that are already installed.

* Added support for specifying which program to use for `make` via the

  `$MAKE` environment variable. FreeBSD users can now instruct

  ruby-build to use GNU make by setting `MAKE=gmake`.

* Modified the post-install process to invoke `chmod` only for group-

  or world-writable directories.

* Added `before_install` and `after_install` hooks for `rbenv install`

  plugins to facilitate post-installation automation.

#### 20130118

* Added a definition for 2.0.0-rc1

* Added a definition for 1.9.3-p374
