Remove 'Solving method' from the solver dialog.

The --method parameter affects only the current "soft thread" (= single
scan), may confuse laymen, and should not matter when an aggregate scan
preset or theme is specified, and those are in general superior and more
encouraged for fc-solve beginners and most experts a like. An aggregate
scan explicitly sets the --method for each scan individually, so there.

As a result, I don't see the point of having the 'Solving method' there.
Perhaps in the future, a more comprehensive GUI for editing the fc-solve
command line will be in order, but that may end up something like thess
monstrocities:
