Fix packrat::bundle() for Windows (#152)
Make sure we return to original dir after bundling
Add 'include.bundles' argument for bundling
Update NEWS, version, autoloader
Split bundle into bundle_internal, bundle_external

When using R's internal tar, we're forced to copy the packrat project to
a temporary directory (because we cannot selectively filter out files
with the internal tar). However, this operation is expensive enough that
it warranted us having an implementation wrapping around R's internal
tar, and an unpenailzed external tar.
Refresh the contents of 'lib-ext' when entering packrat mode (#154)
Clarify bundle() documentation (closes #155)
