Releases for Advanced cache

Fixed a bug in taxonomy caching and hopefully remedied the mistakes I made packaging the 1.4 and 1.5 releases.

I screwed up 1.4 by not including all_patches.patch.

• Feature: #72897 - Block caching =) Not like the blockcache module... no configuration... just apply patch and go. Shaves 1.5 ms off of each page load on my MacBook, anonymous as well as authenticated.
• Feature: new strategy for node cache clearing to accommodate the role-based caching. Needs some eyeballs (that means you, slantview ;-) Also fixes a call to undefined function in the case that forum module is not enabled.
• Bugfix: fixed order of operations in hook_comment.
• Bugfix: clear comment cache on publish and unpublish.

• #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.
• Updating README and all_patches.patch to reflect new forum_cache.patch changes.

• adding an all_patches.patch that combines all cache patches into one for the ambitious and the lazy
• Taxonomy cache not clearing correctly on nodeapi

• adding hook_devel_caches
• Disable node caching for uid = 1.
• #147240 uninitialized array in comment caching
• taxonomy_node_get_terms wasn't keyed correctly

Initial release. Please see README.txt.

Initial commit. Node, comment and taxonomy caching implemented.
