Remove support for out of bounds params in Delete
The existing implementation of Delete on the string classes handles some cases where the range being deleted is out of bounds by clipping it to the valid range. This behaviour can lead to programming problems in the calling code being masked by the fact the Delete method still does something. The new version of these methods does an early return if the parameters are invalid. This change also effectively removes support for negative string sizes from the Delete method, so converting FX_STRSIZE to be unsigned will be easier.
