Anemone3DS v1.3.0

* Massive UI update - A now has multiple functions, combined with the D-pad - you can single, shuffle, BGM and no-BGM install from one sub-menu now! Additionally, there are now touchscreen controls - don't worry, we'll keep the buttons updated for those of you who want buttons, but if for some reason you want to only use the touchscreen now you can. (Thanks to @LiquidFenrir)
* More updates to the QR scanner! It now can scan for QRs automatically without having to press any button!
* Dynamically load themes! That means that even if you have a few thousand themes, Anemone should load relatively quickly, and should never crash. (Thanks to @LiquidFenrir)
* Both themes and splashes are now sorted alphabetically - no more paging through all of your themes just to find one starting with '🅱️'. (Thanks to @Helloman892)
* You can delete items from your SD now! No more feeling like a real hacker and looking through using FBI GM9 (!). (Thanks to @LiquidFenrir)
* Fast-paging (using the Circle Pad left and right) works properly. At last, you madmen with a few hundred themes don't feel left out.
* Scanning a QR that doesn't link to a ZIP file no longer crashes the app, and now just throws a warning. Which means you can go ahead and try to download other CIAs through Anemone's scanner all you like now, nothing will happen.
* The app now tells you when you have too many/no themes selected when attempting to use shuffle - now you can select more than 10, and toggle off the ones you don't want - the feature you never knew you wanted.
* When viewing the preview of an item that doesn't have one, Anemone would previously show the last one you viewed - no longer! You now receive a warning instead, telling you that there is no such preview. (Thanks to @LiquidFenrir)
* START and SELECT finally got their own icons. About time. (Thanks to @Wizzrobes for these!)
* A ton of bugfixes, for that Nintendo level stability... hopefully.
* A whole host of grammatical and aesthetic changes, to make everything look nicer™️
