- map modifies source collection
- arrays are passed by reference
- resulted in remapping g:bundles into list or directories

- was beaking case when bundle is already installed(downloaded) but not
configured
- should not affect other cases as adding require is pretty safe

- pass booleans instead '!'

- BundleClean now requires confirmation

- removes unused directories

- closes https://github.com/gmarik/vundle/issues/#issue/2
- thanks http://github.com/dag for reporting

- so it's ready to use right after installation

- vundle.vim - entrypoing and loader
- config.vim - configuration and runtimepath management
- installer.vim - installation and docs
