All images have been moved to the /img/ folder in order to fully
separate qml from images. The .qrc file allows qml to use the images by
appending the qrc:/ prefix before the abstract path to the image.
Note that the .qrc file is also check at compile time, which further
enhances the confidence the lack of errors.
Some of the images are not used in the QML, but instead directly passed
through to the OpenVR API. These have not been added to the .qrc file.
Elements work like they've always done, this just moves the commonly
used components away from the global namespace.
The qmldir file still does something, although at this point it is
unknown exactly how it's used and whether or not it could be changed to
simplify imports across the block.
The PTT controls were grouped in a ColumnLayout with the microphone
device and volume controls. Grouping the microphone controls together
mirrors what is done with the mirror device controls.
The mirror selector is a sub part of the volume slider. This could be
changed in the future to have the slider be a top level component that
contains both selector and slider.
For now the way to go is to have the mirror device and audio device
selectors as different components instead of trying to inherit from a
single component and filling in the necessary function calls.
This is because some function calls are nested inside other components
and would be very messy. Perhaps in future commits the selectors will
inherit from a single parent.
