* Fix a bug where some files sizes were sent as 0. * Make FileManger.sizeForItem(at:) a UInt. The docs specifically say that FileAttributeKey.size returns an unsigned long long so I have no idea why we were returning a Double here… * Add the maxMediaUploadSize property on ClientProxy. * Use the maxUploadSize to set a target video size and to show a file too big error. * Refactor media upload parameter order.
