pluginlib_touchscreen: Rework API to offer wait-for-button APIs.

Browse source 
The old touchscreen_get() needed an external button_get() call. Now two APIs are
added that do this call internally. This way they behave similar to get_action.

The old API is preserved (but renamed) since it's used in reversi.
