Update bankscreen to include searchBox

Adjusted __find to read a different point in the bank, so it will still detect the bank while the Search Box is open.
Adjusted Kevin's latest Withdraw overloads to include waitTime, and removed any Carriage Return characters from the getMouseOverText for long item names that span 2 lines.
Added isSearchOpen to determine whether or not the Search Box is open.
Added isButtonActive to determine if the search button, or the Notes button has been activated.
Added searchBank to search through the bank using the in-game search feature.
