[lime-dev] New flavor for new LibreMesh release

Hi all, OpenWrt 18.06 is just around the corner with fun new stuff, like options to encrypted 11s mesh & support for tons of new devices! To create a LibreMesh release that satisfies all tastes, we should think a bit of new flavors, meaning the combination of preinstalled packages. Some points to consider: * There is a new lime-proto-babeld plugin allowing babeld routing * The lime-proto-bmx7 plugin and BMX7 itself became way more stable and has various advances over BMX6 * Using encrypted mesh requires wpand-mesh-{openssl, wolfssl} installed, aka big crypto libs * The lime-app shows some basic infos which could satisfy basic user requirements. I'm happy to merge flavor PRs and build them on our new snapshot server for all common targets. Sunshine, Paul
