Updating to use rsyncwrapper 0.3.0

rsyncwrapper 0.3.0 is a fix to correct the order of imports and exports.
rsync --include's before --exclude's allowing explicit selection of
files to rsync, while rsyncwrapper < 0.3.0 --exclude's before
--include's, causing all imports to be ignored. This allows wildcard
filename includes on OS X, where filename wildcards in rsync src will
fail.
Bump to 0.5.0 and update release notes in readme
