#1193 #1161

[artemii235]

Need to fix WASM, which will take a bit more time.

[artemii235]

Finished the fixes.

[cipig]

retried #1161 with "{\"method\":\"electrum\",\"coin\":\"KMD\",\"servers\":[{\"url\":\"electrum1.cipig.net:30001\",\"protocol\":\"SSL\"},{\"url\":\"electrum2.cipig.net:10001\"},{\"url\":\"electrum3.cipig.net:10001\"}]
electrum1.cipig.net:30001 is wrong, 30001 is WSS port, the other 2 electrums are correct

now mm2 shows this errors only every 5s

not several times per second any more, and mm2 is usable

Using this mm2 with a few bad electrums (wrong url or port) no longer flooded logs with errors. Error messages still present, but appear at a much less frequent rate (every half second or so)
