YAFT-64 update clogdash <parent> and pom versions to 11-SNAPSHOT

Adrian--pointing this PR at Yaft master but before you consider merging it, I recommend creating a Yaft 1.3 (Sakai 10) branch first.  I've also updated the version from 1.3.0-SNAPSHOT to 11-SNAPSHOT.  This aligns Yaft master with Sakai trunk version practices.  However, if you would rather have clog master versioned 1.4.0-SNAPSHOT I'll happily adjust the PR.
