Fixed a few issues with multiplayer, after just doing a playtest:

• Fixed the position of the player menu in multiplayer.

• Fixed the scaling of the "Sell All" menu in multiplayer.

• Fixed the Merchant discount blessing to not just give you a 75% discount no matter what.

• Fixed a bug where players would not be able to purchase an item if they only had enough for it on discount, but not enough for the base price.

• Adjusted the size of the player message box so that it is always on screen in multiplayer.

• Adjusted the size of item count text when in Multiplayer so that it doesn't wrap.
