As suggested by Oliver "giller" Fieker oli@new-lan.de in bug 10592 I added the functionality to use the squid as ram-only cache.

Further it defines the maximum_object_size_in_memory as 2% of the in the webif defined "Memory cache size". The maximum_object_size_in_memory should have a useful size of the defined memory cache and I don't want to create another variable which muste be fulled in by the user.
