* infobox: added wifi channel, airtime and batctl nexthop
* simplify
* kill all semicolons
* update data locations
I'd suggest that channel information go under nodeinfo. Airtime and nexthop are changing variables which should go under statistics.
* filter out nodes with faulty nodeinfo
* additional nexthop key
The nexthop to the batman gateway has now been made available in gluon master where it will be called "gateway_nexthop" the "nexthop" key is also currently in use and should eventually be removed
* sidebar/node: cosmetic changes to gateway/nexthop
* remove data validity check
* move wifi helper function to sidebar/node
* cosmetics
