Review request for Plasma and Aaron Seigo.


Changes
-------

when the predicates are created check if there are some devices that now have an action, while before they didn't; opposite thing on remove.


Summary
-------

This patch uses a KDirWatch to watch the folders where the predicate files are in. If one of them gets created, modified, deleted, it updates its data so the applets using it receive a dataUpdated() and can adjust their things.

Testing (updated)
-------

tested, works. the notifier changes its "x actions for this device" instantly. (the notifier needs a fix for it anyway, since the actions themselves aren't changed. i'll do it once this is committed)

However, maybe would be a goog idea to cache somehow the value of the function predicatesForDevice() in order to avoid to parse everytime all the predicates and so parse only the new or changed ones, cause it seems to have quite a big impact on performances.


Thanks,

Giulio
