This minor release resolves the mysql installation bug and a possible DOS vector in cache image generation.

• #147977 fixing node cache so that the same rules apply to loading the cache as to setting. #147456 allowing a variable, 'advcache_node_exclude_types', determine whether a node type should be excluded from caching. Defaults to array('poll') so polls work. Rolling against DRUPAL-5-1
• Re-rolling all patches against DRUPAL-5-1
• #148279 by aymerick and robertDouglass: add forum caching. Same warning as with taxonomy caching applies here... if db_rewrite_sql is rewriting taxonomy queries, as is the case in taxonomy access type modules, this patch should not be used.
