YAFT-64 updated <parent>, pom versions to 11-SNAPSHOT

Adrian--pointing this PR at Yaft master but before you consider merging it, I recommend making sure your 1.3.x branch is up-to-date 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 Yaft master versioned 1.4.0-SNAPSHOT I'll happily adjust the PR.
