Automatic cache clearing

[Leonard]

Scheduling is a good idea, But Snakeoil don't have any scheluding program installed I think. Will have to double check and see if it's possible. This cache clearing thing is only experimental feature for now, to see if if it does anything, so far I find it doesn't make any difference, but still early stages as I havn't tested this in detail.

I assumed linux would also have some kind of taskmanager running just like Windows. If not, it may be better not to introduce it as well as it will also consume processor power.
On the other hand; I notice that after a while (several hours) loading a new playlist takes longer in my setup (USB + casper-rw).
Below a screenshot of how much memory was used before clearance. Good to have the option to do it manually as well!
