Fixed various start/stop issues

Fixed frame handlers being removed and not re-added after the hardware interface was stopped.
Changed the order of how we manage working set activation to avoid a possible deadlock between the Juce message thread and the callback mutex.
Fixed issue with windows executable not being packaged into installer.
Fixed accidentally drawing timed-out working set icons.
Clarified start instructions.
