Update for app framework removal
Changes:
- Remove the autobuild scripts and config.xml used by the app
framework widget build.
- Update the qmake files to just build a "hvac" binary and install
it into /usr/bin by default.
- Remove the code in main.cpp that handled reading the WebSocket
command-line arguments and passing them to binding related
code.
- Add setenv of QT_QUICK_CONTROLS_STYLE to "AGL" to get the AGL
styling used. This replaces a global environment variable
definition tied to the old app framework, and makes it more
obvious that the style is required for the app to properly
work.
