Bug#778642: Memory leak patch

[Phil Davidov]

I put together a patch for memory leaks in xfce4-power-manager-1.4.1
based on a back-port of upstream fix
(https://github.com/xfce-mirror/xfce4-power-manager/commit/18ead01edbc013abf620e3a9ea31eabcad1ae267)
and additional memory leak found using valgrind.

Tested & appears that the plugin memory footprint is now stable.
