In the existing code pCharPos is manipulated directly without being
reset. This means that for the second iteration it is at the end of
the range instead of the start. This CL introduces temporary iterators
that are intialized to the value of pCharPos and then manipulated to
avoid this issue and having to reset pCharPos.

This makes the caret appear (again?), blink, and fixes its positioning
to be a little spaced from the last character.
Known issue: when the edit is empty, the caret is not necessarily
aligned with where the text will be.

Through out the code base there are numerous places where variables
are declared using a signed integer type when interacting with the
string classes, since they assume that FX_STRSIZE is 'int'. As part of
changing the underling type of FX_STRSIZE to be unsigned, these
locations are being changed to use FX_STRSIZE. This is necessary as
part of converting the type, but has been broken off into a separate CL,
since it should be low risk.
Some related cleanups that are low risk are included as part of
this CL.
