qmpfw: Quick Mesh Project legacy firmware generator (deprecated)

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

Rebuild all remaining config files
Only diffconfig is stored now (not all the config)
Adapt the configs to new bmx6/luci-app-bmx6

Rebuild nsm5 and ubiquiti products config filesges. Lines starting

targets.mk and config files adapted to the new version of qMp based on Openwrt attitude adjustment

Regenerated all config files to add the new bmx6-luci and in some big nodes luci-qos and luci-radvd

Rebuild all config files, ssh-keys is not selected by default

Rebuild of rspro, nsm5 and alix configurations

Re-build nsm5 config file, references #161.
