ticker based wakeup

[fossfreedom]

at the moment there is one field that is used to wakeup the next sweep of sensors. This doesnt work too well with sensors that dont need to run at the sweep time e.g. ipaddress sensor

It would be better to have a one second timer - every sensor then can have a either a defined "number of seconds to wakeup" or use the one default field to wakeup.

Doing it this way opens up the way for every sensor (inbuilt and also user defined) to have a "use default" checkbox / own "number of seconds to wakeup" value.
