@garwynn but I saw you also asked this in TD's thread so thought I could at least post these descriptions that are in the CM12 rom for those items.
Wi-Fi-Verbose logging - Increase Wi-Fi logging level, show SSID RSSI in Wi-Fi Picker.
Aggressive Wi-Fi/cell handover - When enabled, WiFi will be more aggressive in handing over the data connection to Cellular, when Wi-Fi signal is low.
Allow Wi-Fi roaming scans - Allow/Disallow Wi-Fi Roam Scans based on the amount of data traffic present at the interface.
