Change node.py path collapse back to a "." separator instead of a pipe
Change the views.py completer separator back to a period instead of a pipe
To sort of restore the original Graphite's dotted path processing, I implemented OpenTSDBFinder.drill_recursive to run through the branches, starting at the root, and find all of the matching branches and leaves. It's definitely not optimized and the matching on nodes that contain periods (e.g. FQDNs) isn't perfect, but it kinda works and now you can request something like phx.tsdb.tsd-1-4.phx.mysite.com.tsd.hbase.rpcs.put or phx.tsdb.tsd-1-4.phx.mysite.com.tsd.hbase.rpcs.* and it will graph it all.
Restore node.id as the name for browser.js
