Move misc/gretl to math/gretl; add secondary category of finance

	gretl is used in the mathematical analysis of time series,
	and has a functionality that is similar to various statistical
	and signal processing components of it++, octave, scilab,
	R, numpy/scipy, etc. -- most of which are in the math
	category.  It should really be placed there, rather than
	in misc.  In recognition of the fact that it implements
	some methods that are commonly (but not exclusively!) used
	in econometrics, it should also be given a secondary listing
	in finance.  (In my opinion, however, it shouldn't be given
	a primary listing in that category, because most of the
	ports there deal with the nuts-and-bolts of accounting,
	payment methods, taxes, and stock tracking.  To my knowledge,
	the only ports now in finance that remotely resemble gretl
	are quantlib, xtrader, and qtstalker, all of which employ
	simpler methods that are more specific to financial time
	series than are the more general methods in gretl.
