Screen off timer to not affect wampy

[krebstaebchen]

An enhancement to make wampy act as the lyrics screen with "keep screen on when displaying lyrics" checked, so the screen would turn itself off when used casually, but would keep the screen on if wampy is active.
As a casual user I don't use wampy all the time, but when I do I love to keep the screen on when its active. On the other side, It would be great if the screen turned itself off when I listen to music casually, e.g. if I forgot to turn it off or it turns itself on accidentally while in my pocket.

Wampy-specific screen off timer will confilct with standard timer:

Let's say standard timer is set to 30 seconds and wampy is set to keep screen on. Every time you toggle wampy on, it must save standard timer value, set it to "Off" and restore on toggling wampy off. I think that these values are stored somewhere in NVRAM (or whatever that place with system settings called) and could be changed without hacks. However, changing those values won't stop standard timer - it had to be switched off manually (or by talking to qt Settings object asking it to change settings, thus stopping timer).

Possible, but will take some time. Not a priority, check back in a couple of months I guess.

I suggest setting standard timer to "Off" for now and using power button.
