- Improved behavior in the networking backend. The wired/wireless wnettools instances now refer to each other, and get passed on to connection threads as well, which simplifies passing settings for external program usage. Also removed some unecessary creating of duplicate wnettools instances which ended up causing some issues. - Fixed bug where dhclient was being used as the dhcp client even if it was selected in the options menu. - Fixed a typo in the connection commands used for ralink cards. - Fixed the wrong cli option for releasing a dhcpcd lease. - Monitor.py no longer calls for an auto-rescan if the daemon is currently connecting to a network. - Cleaned up some comments and simplified the logic in a few methods/functions.
