READEish file updates for 0.5.2
Tweak gh-pages-update.sh

This script generates a new gh-pages index.html and copies javadocs
for the release to /javadoc/$VERSION/ and /javadoc/current/.  This
commit makes its detection of whether the gh-pages branch already
exists more robust by using a git plumbing command instead of checking
file existence in the .git directory.  Also fix outdated wording
talking about wikidoc in one of the messages it prints to console.
Bring release instructions up-to-date
Make release.sh push HTML documentation to S3
Set 0.5.2 release date in upgrade instructions
Merge branch 'issue_808' into titan05
Add sleep to testIndexQueryWithScore

ES rebuilds indexes asynchronously, but testIndexQueryWithScore
commits and then immediately tries to search on what was just
committed.  Maybe we should change the ES test config to force an
inefficient full refresh on every write for testing purposes.  For
now, I'm adding a sleep to the test instead.
