Auto smart comments and multi response

[MaxBrokhman]

• Added smart comments to enable mutations for all tables by default
• Default naming changed, prefix removed and pluralized table names used instead
• To all mutations created by this plugin added isMultipleMutation flag in context
• Nested input types removed from update mutation patch type to make sure that when used with nested mutation plugin, in update mutation patch type nested mutation fields will not be available. This is needed, because currently both plugins define new resolvers in order for them to work which not allow them to work at the same mutations.
