BugFix: More 5GHz channels, 900MHz nodes now found by 'board_id'
Added 'non-US' 5GHz channel numbers. Device band was determined by channel, 900MHz and 2.4GHz have some of the same channel number and the script had a hard time telling which was which. This has (hopefully) been fixed now. Since there are only 3 AREDN compatible 900MHz devices, it was easier to just find those certain board_id's. This also allowed channel #4 to be added back into the list for 2.4GHz. (yes it was a hack but mostly worked :) ) Additionally, I've been trying to optimize the map_function.inc file. A couple of the functions in that file consume 90%+ of the time it takes to render the webpage. (load_LinkedTO() is a beast!) On the cloud server this can sometimes completely stall the script(s) and fail to load the page at all.
