Make sure all files get synced to svn repo

When rsync compares a freshly-built source
against a previously-synced destination, it sees
matching timestamps on both sides and skips any
file whose size also matches, even if the content
differs. The -c flag makes rsync compare MD5
checksums instead, so it correctly detects the
content change.
