TopFit

• fixed items with the same itemID showing up multiple times in the force item menu
• fixed forced slots not being correctly updated when adding or deleting a set in the options frame
• fixed bug when trying to calculate blood tank preset. Again, if you get an error with it from before this version, click the defense cap value, and overwrite it with <Enter>
• Deathknights can now Dualwield. D'oh
• Added first parts of plugin API. Documentation can be found at http://github.com/Mirroar/TopFit/wiki/API
• Stats / Caps editor and virtual items UI use the new plugin functions.
• Virtual items can now be included in set calculation, to see what would happen if you had a certain item. Items are not sanitized (you can calculate with a level 80 item or a plate item as a level 70 priest) and any calculation including virtual items will result in the set not being equipped.
• Shamans and Warriors can now choose to simulate dual wielding or Titan's Grip for a set, indifferent of their current spec.

When forcing dualwield as Shaman, items for offhand only will still not be used in the calculation when not specced into enhancement. As a workaround, add that item as a virtual item.
