[PATCH] Profile: Display VPM-B rather than GF when in VPM-B mode

[Rick Walsh]

If we are planning a dive using VPM-B with +x conservatism, we want to
print "VPM-B +x" at the top of the profile, instead of "GF xx/yy".

Accordingly, the variable gradientFactor in profilewidget2.cpp is renamed
decoModelParameters to reflect what it represents.
