Needs +Widgets for option UI to work
WIP on Softrock plugin, not working yet but compiles
Removed all implementation details from DeviceInterface.
Added a new DeviceInterfaceBase class that all plugins derive from, with common implementation details
Update to move all DeviceInterface implementation details into SDR, since DeviceInterface is now totally abstract.
Implemented Audio input support for device plugins.
General clean up
Added InitSettings and Perform to DeviceInterfaceBase
Update Example, RTL, File devices to use DeviceInterfaceBase
Working Softrock plugin, but hardwired for Fifi
Moved default ReadSettings and WriteSettings to DeviceInterfaceBase
Reset (delete) all .ini files from Options dialog now works
Updated settings to allow device classes to easily set initial ini file defaults and still use DeviceInterfaceBase::ReadSettings()
Softrock plugin now supports all the same devices as internal.  Clean up settings so each device has it's own complete ini file.
Removed internal Softrock device from project, replaced with Plugin
Missed 2 references to softrock.h
make sure we re-read settings when displaying SDR options
