QmlDesigner: Improve usability of boolean animation curves

Browse Source 
Boolean animation curves are now painted from min to max of the value range
instead of from 0 to 1. This allows to see value changes when the curve is
loaded together with other animation curves of different value ranges.

Boolean curves are now forced to be step interpolated.
If the user tries other interpolation types the request is denied and an
error message is written in the new status line.

Added a status line that displays the current frame number by default and
an informative text in case the user did something forbidden.

Respect the current state when populating the curve editor.
