Implemented ObjectSpace.count_objects to count the number of allocated objects for each type
Merge branch 'master' of git://github.com/mruby/mruby
ObjectSpace.count_objects was incorrectly checking if an object was already freed. Amended the count_objects test to ensure the correct distinction
Change in formatting for os_count_objects to be consistent with other functions.
