support findred and --branch with file matching options

* findref: Support file matching options: --include, --exclude,
  --want-get, --want-drop, --largerthan, --smallerthan, --accessedwithin
* Commands supporting --branch now apply file matching options --include,
  --exclude, --want-get, --want-drop to filenames from the branch.
  Previously, combining --branch with those would fail to match anything.
* add, import, findref: Support --time-limit.
