1) Updated `ALLabel` to latest version (`1.0.1`), which fixes a bug where `preferredContentWidthSize` wasn't being set correctly on iOS 8
2) Updated constraints on `ALMenuCell` to get rid of auto layout constraint issues
3) Added `identifiersToNibsDictionary` as private property on `ALTableViewCell`. This is used to instantiate table view cells (instead of dequeuing, which could leak)
