New features, better performance…

+ Ajax requests now use asynchronous requests.  This avoids issues with (esp.) the VSX-1022-K causing webpage hangups when making control requests.
+ Add an 'Input Switches' page that can (for the moment) switch the VSX-1022-K to any of its inputs on demand (we will add in tables here later for devices that register specific function input keys and/or command macros).
+ Add a 'Volume Levels' page that can (for the moment) ratchet up and down the VSX-1022-K's volume levels (we will add in tables here later for devices which register a volume up/down key set and/or command macros).
+ Adds a 'USB-UIRT Info' page (now just a template) that will (soon) display the results of listing commands parsed from the LIRC configuration file.
