Fix #282: remove PPP packets from ath-qmp-tiny-node
Remove ath5k dependency from ath-qmp-tiny-node to keep images small
Adds a new way to generate/store the configuration files for each target: There are profiles (such as ath-qmp-small-node) which are shared between all similar kind of devices (i.e ubiquiti devices) And individual configurations (optional) which can be used to specify extra options for the device
