Subject: [PATCH] Bugfix #5144

Nkey panel for creases median didn't work properly. Now it does as follows:
- if set to 0 or 1 it applies that value to all creases
- else it adds the diffference of median crease value and the button value

Bugfix #5122

Paths drawing option for Poses now uses entire startframe-endframe range.
Before it skipped the last frame for drawing.
