RompR 0.16.3

My pseudo-random version number system continues!
There isn't much new in this release. I've made a few minor tweaks and bugfixes and a couple of speedup improvements.
But the biggest change is that the music Collection is now cached, which massively speeds up loading the albums list and the files list.
There is a new option in the Configuration to make RompR update the Collection every time you load the page - enabling this option basically reverts RompR to the old behaviour. Additionally there are new buttons to force a Collection update and to force a complete Rescan of the entire collection.
People running mpd/apache on slow machines (eg Intel Atom/Raspberry Pi/hacked NAS devices) might find this update to their liking.
Enjoy the music :)
