* Implemented the 'RDXPORT_COMMAND_AUDIOSTORE' web API call in
	'web/rdxport/audiostore.cpp', 'web/rdxport/rdxport.cpp' and
	'web/rdxport/rdxport.h'.
	* Added an 'RDAudioStore' class in 'lib/rdaudiostore.cpp' and
	'lib/rdaudiostore.h'.
	* Modified the Desk Gauge widget in 'rdlibrary/disk_gauge.cpp'
	and 'rdlibrary/disk_gauge.h' to use the 'RDAudioStore' class
	[fixes GitHub issue #000035].
