Fixed type bug in SwapModel : changed from using word.type to word.getWordType <= the former gets the type from Element, which is always one
Adding Swap, Removing Swap, Swap/Revoke seem to be working properly.
NOTE: Add randoms buttons are not working because they are contacting with the old swap data in Board instead of new data in Swap.
Swap seems to be woring properly. Testcase: add random adj, adv, noun, verb , swap; then add add noun, verb, for adj, adv, swap => each side got two types of words.
