Update: Smarter item builds, some fixes

[quote=Matt]Just put out an update that takes item recipes into consideration when calculating stats. Only the last (up to) 6 items that are not used up as components will be counted towards stats in your build. Any component items that will go into creating future items are grayed out in the item list (and excluded from stat calculations) so you can see that, and the key 6 items will stand out more. The algorithm is a little weird so, if you spot any situations where it chooses the wrong items please let us know and we'll investigate! We've also fixed a few bugs, particularly one in the build editor which made it impossible to delete champions after you added them.[/quote]
