[William Grant <me@xxxxxxxxxxxxxxxxxx>]

William Grant has proposed merging lp:~wgrant/launchpad/bugtaskflat-v2-indices into lp:launchpad.

Requested reviews:
  Stuart Bishop (stub): db

For more details, see:
https://code.launchpad.net/~wgrant/launchpad/bugtaskflat-v2-indices/+merge/105435

Add date_closed and latest_patch_uploaded sort indices to BugTaskFlat for all targets. Both are used to satisfy both filters and sorts.
