README.md problems

[ElixsDev]

The "source" link at the bottom of the "URL parameters" table is broken, the page it links to doesn't exist.

In the "AJAX endpoints" section in the second table, there is no description for the variable "recc" (says unknown)
"&r=SFVMa" only returns aircrafts that the receiver "SFVMa" received, so you could replace unknown with "receiver"
