[development] Patch reviews

Hi, While discussing http://drupal.org/node/130991 on #irc I got this: "i think its well over the level of comprehension of most except for a select few maybe, its not like no one is interested in it, far from it :)" While I actually disagree -- the code is not that complicated not at all -- you can still help, lots. I have followed up with a brief functionality description to encourage *functionality reviews* I will do the same in the future so people without deep code knowledge can help out. Thanks for that. ChX
