[applets/batterymonitor] Improve UI for power management inhibition
This patch improves the UI for inhibiting power management and seeing which apps are automatically doing it. Here are the changes, explained:
- Use less jargonistic terminology for the feature itself, and remove the explanatory tooltip which is no longer necessary
- Show the full list of apps which are inhibiting power management, because we have the space now that app icons are smaller
- Correctly show and hide the list of inhibitions based on count and Whether or not the user has independently suppressed PM
- Leave a bit more room for long reasons and alert translators to minimize string length as much as possible
