Pass log context number to CocoaLumberjack if defined
MR_deleteInContext: now checks that the managed object is loaded in the specified context before deleting it.
Use existingObjectWithID: directly rather than checking the MOC reference.
Typo fix.
Converted spacing to tabs.
Added test for MR_deleteInContext: across multiple contexts.
Only fetch once when calling `+ (NSFetchedResultsController *) MR_fetchAllSortedBy:(NSString *)sortTerm ascending:(BOOL)ascending withPredicate:(NSPredicate *)searchTerm groupBy:(NSString *)groupingKeyPath;`
