[Ovmsdev] Duktape heap memory management

[Craig Leres]

Progress!

I was a little worried because I was measuring ~2 ohms between the 
antenna pin and ground but I tried it anyway and I have signal now. I 
saw crashes the first few times the cell network came up but it 
eventually settled down and is working now. Maybe an edge case in the 
dhcp code vs. first time network registration?

FYI I'm running 3.2.016-377-g1e6da7e5 (for-v3.3 branch).
