[pvr.vuplus] Bump addon to 1.9.14

This is jdembski's rebased PR to update pvr.vuplus to latest version - opdenkamp/xbmc-pvr-addons#281

I tried to contact him in the forums but couldn't and I can't find an email or any other means to have a word with him.
Since this PR is waiting for 4 months now, I hope he doesn't mind.

No changes from jdembski's original PR except the bump version 1.9.11 -> 1.9.14
