    Repair browser client dropdown buttons

    Angular-ui-bootstrap as of version ~0.11.2 does not want bare
    "dropdown-toggle" attributes within action link tags.  When present,
    they prevent the dropdown button from opening.

    Avoid org tree retrieval race condition on patron app

    Avoid calling egOrg.ancestors() during startup, because the org unit
    tree is not guarantee to be available until startup has completed.  This
    was causing an occasional JS excpetion in the patron app pages, which
    prevented the pages from loading.

    The error in question:

     TypeError: Cannot read property 'map' of undefined

*** Before, grids had no way to ignore link fields and one could add them to the grid.  This ended up showing a pile of JSON.  Now the grid knows how to ignore fields (and we ignore current_copy on circ-ish grids).

    Ignore the "current_copy" field, we already get that separately
