Add currently running openwrt release info

[1alessandro1]

It would be nice, when someone updates the firmware, to understand which version is currently running. I remember you had already addressed this in bananawrt_release, and it would be nice to highlight the "current OpenWrt build" just before the "Loading releases" message, something like:

[INFO] Fetching releases from GitHub...

Last 4 available releases:
