#149 Password boxes too small

[Grósz Dániel]

Password boxes are small, they do not use the full width of password windows (see screenshot). With Oxygen they are OK.

[Thomas Luebking]

Client bug, there're various fieldGrowthPolicy's
On OSX the default is FieldsStayAtSizeHint, for Plastique (and likely Oxygen) the default is ExpandingFieldsGrow.

(Ie. if you uncheck "behave rather maccish", this will change)

I'll try with the new(er) AllNonFixedFieldsGrow for the "maccish" case, but it's the clients job to pick an explicit sensible variant.

If you compile yourself: stylehint.cpp:211 - return 1 (plastique behavior) or 2 (AllNonFixedFieldsGrow)
