the code in these two methods is largely similar, particularly with regards to window
placement issues. Where possible, need to work out inconsistencies between the use of the
command line in main() and the use of Preferences in startInternal, as their functionality
should be roughly on par with one another.

break the functions out of main() where necessary so that they can also be used by
startInternal() or even startExternal().

this code is heavily tested and very core in its function, so refactoring must be done very
carefully to avoid regressions. in both cases, the code may look like spaghetti, but in fact all
of the functionality that's there is essential to running things properly.

fixed as part of the 0136-0140 series.
