Moving PowerDevil to kdereview

[Dario Freddi]

Hello everyone,

I am writing this mail to inform you I have moved PowerDevil from 
playground/utils to kdereview. PowerDevil is a Power Management system for 
KDE4.

PowerDevil's aim is to be lightweight, feature-full, configurable, based on 
Solid only and fully integrated with the Desktop Environment. It is splitted 
into various components, a KDED module, a KCModule, a KRunner, a Plasma Engine 
and a Plasma Applet.

The core is the KDED module. Polling was removed thanks to a system that sets 
the polling time to the next upcoming idle event. Every time the polling 
function is called PowerDevil calculates the minimum time for an idle event to 
come, and sets the timer accordingly. For example, in a scenario where you 
have a lot of events in a small amount of time, PowerDevil polls the system 
every minute. For detecting system activity, it uses the same grabbing system 
used previously in KDE4Powersave.

The KCModule handles configuration of the Daemon. Having a dedicated 
application for it seemed to me redundant, since you can have it by using 
kcmshell4. PowerDevil has 2 kind of configuration: a general one, and a 
profile-based one. You can create new profiles and assign them to particular 
events, PowerDevil will take care of kicking them in at the right time.

The KRunner acts like a shell of PowerDevil. By typing set-profile, set-
governor and so on, you can change on the fly what you need.

The Plasmoid should be what the system tray was for old Power managers, and it 
should basically have the same features as the KRunner.

The code I'm putting in kdereview includes the KDED module, the KCModule, the 
KRunner and the Plasma Engine. I'm not so good with Plasma, so I tried to 
backport the current battery plasmoid and extend it, but with no luck. I'd 
really need some help on this side.

Though the core is already working and it's fully-functional: it's being 
tested since a pair of months by KDEmod users, and they're pretty satisfied 
with it. The KRunner is also stable and functional.

The code has no Krazy issues, compiles with no warnings and it's fully 
i18n'ed. I'd like to move it to kdeutils trunk, if approved. It still needs an 
usability review, a native english speaker's review of strings, and some help 
on the Plasma applet.

Thanks and Cheers,
Dario
