Since we use that class to lookup the NSBundle using bundleForClass
use a more specific name to avoid any clash with any othe liferay
extension. I couldn't figure out from the documentation if that is
only resolved using the class name, but found some warnings on
stackoverflow and better be safe than sorry for what it costs.
It was only used on OS X and couldn't be used by the FinderSync
extension since that one runs in a sandbox. So use the same system
to load images in the legacy extension by shipping them in the
extension bundle instead of the owncloud.app bundle.
This is also given that the legacy extension needs padded icons
while the FinderSync one needs unpadded icons.
Do not request the status of all entries in the cache. Instead force Finder
to request the ones that it deems necessary by keeping the old statuses
in a separate dictionary which are only used while the new status arrives.
removeIcons isn't called and clearFileNameCacheForPath was always
called with a "nil" path.
Remove the return value of askForIcon which was always 0, and use
that value explicitly at the only call site.
Remove the "-1" code path in iconByPath since setIcons prevents
-1 from getting into _fileNamesCache in all cases.
The client (in this case mirall) tells the Finder plugin where to get the icons.
This enables installation in different locations and in branded clients.
Re-retrieve all icons for a path in case we receive UPDATE_VIEW.
(But in contrast to previous code, don't delete the icons which then
would have caused screen flickering)
