app, libgimp: add increment parameters to gimp_prop_widget_set_factor()

Step and page increments can't be reasonable calculated or guessed
based on the GUI widget's factor, so pass them each time we call
set_factor(). This change reintroduces sane ranges for the levels tool
for != u8 images again.

Bug 701159 - Wrong name in transform tool dialogs...

...when acting on a path or selection

Factor out the code that checks if an active item exists and if it's
transformable (not locked etc.) and use that function in more places.
This fixes both the wrong dialog labels and the tool running into
broken states when the selection or a path are being transformed.
