2.1.2: Quiet decloak. Support ESSIDs with commas and trailing spaces

Decloaked ESSIDs will have a "*" next to their name. For #78

While testing, I found that Wifite did not parse Airodump's CSV correctly.
Specifically, ESSIDs with commas or trailing spaces.
Fixed in this commit.

Also fixed hidden ESSID detection introduced by the new CSV parsing logic.
