Rework wireless to use wpa_supplicant more, add CONFIGSECTION support

CONFIGSECTION will be useful later on for integration with autowifi.
It'll allow WPA configurations to be stored _in_ the profile, rather
than separately.

Experimentally, WEP/none support has been migrated to wpa_supplicant.
Support for string keys has not yet been merged.
