Added support for disabling padding between segments for code

Fixed potential bug where code size is calculated by taking the page size of combined segments rather than the combined padded segment size. This could be a problem, for example, if two segments add up to require two pages of padding.
Fixed potential bug where memory-size is used for codeDetails.rwSize; this counts .bss which is not in the file
