[Xfce-i18n] Power manager translations

[Masato Hashimoto]

Hi Ali,

There seems to be some untranslatable strings related the Inhibit plugin.
What I confirmed as follows.
 
* Tooltips of the Inhibit panel icon
* Context menu of the Inhibit panel icon
* Notification message when the Inhibit plugin is running but the xfpm is not running.

Regards
