Adam Seskunas 1e6c1b672b tdf#114441 Convert use of sal_uLong to better integer types 
In ctrlbox.cxx, nCount and i were changed to sal_uInt32 because
aFontSizeNames.Count() returns sal_uInt32.

In valueset.cxx, nFirstItem and nLastItem are only used in a comparison
with a value of size_t. They were both changed to size_t because
nLastItem contains the product of tools::Long mnVisLines and
sal_uInt16 mnCols where tools::Long can be 64 bit in some cases.
