XML Output doesn't contain additional verbosity info

[Varunram]

Issue reported on Stack Overflow. As verbosity increases, the standard output to command line increases significantly. With XML output however, it doesn't seem to improve (although there are a few additional tags, it is not comparable to standard output).

XML is not intended for debugging. It is intended as an interface for other programs to more easily parse Nmap scan results. It does not change significantly with -v because it is intended to be complete in any circumstance: there are many things in XML output that do not show up in Normal output without -v, or which do not show at all. E.g. port state reason info is always in XML, but only in Normal with --reason or -vv.

EDIT: If there is a specific line of output or piece of data that needs to go into the XML, please open a different issue for that.

Thanks! Cleared it up.
