Added some truncation constructors in Nucleus

Added some extra constructors that simply truncate from a type which has a higher number of bits. The new constructors are: - Byte from UInt - Byte from UShort - SByte from Int - SByte from Short - UShort from UInt Also added an implementation of the RoundUInt function using the UInt from Float constructor, which had to be fixed since it was using createFPToSI instead of createFPToUI.
