Cache increment/decrement with initialization when missing value
This patch makes incrementing/decrementing values using Rails.cache easier, particularly if one uses memcache. For proper use of incr/decr using memcache see http://code.google.com/p/memcached/wiki/NewProgramming#Proper_Use_o...
This patch allows passing in a block to the +increment+ and +decrement+ methods of Rails.cache, similarly to how +Rails.cache.fetch+ works.
Note that the implementation for mem_cache_store takes some pain away by storing the initial value raw and using +add+ instead of +set+, and retries an increment/decrement in case +add+ returns +false+.
This patch also adds a missing test to the increment/decrement behavior test, namely the one that tests for +nil+, and has modified mem_cache_store so that it's behavior is consistent with the other cache stores.
