remove redundant else clauses
Switch gallery to save and load all nupkg package blobs using lower case blob file paths so that we get effective case insensitivity to package IDs. I think InvariantCulture is the standard culture for comparing package IDs.
Fix the OData feed on preview which was a) throwing null refs b) missing a whole lot of data in fields (now that they are coming from Lucene instead of the DB) causing a blank UI to show once the throwing thing was fixed. Removed PackageIndexEntity class as it wasn't pulling much weight.
Add unit test for driving the V2 feed using the Lucene Index!
Ensured unit tests passed.
