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.
