- the setting "Standard and Style" only affects new dimensions, thus it must be italic
- fix bug that the Property 'LockPosition' appears for dimensions -> this is an option for views and thus must be hidden for dimensions
- since tolerances are in the vast majority fractions of a millimeter/inch, set its stepsize to 0.1
(I hope I did it right in handleChangedPropertyType.)
- fix inconsistent newlines in TaskBalloon.h
- improve wording for a heading
