app store mobile ui

[0x70b1a5]

Problem

• App store mobile UI stinks
• KinoUpdates + appstore widgets don't have a tag for good mobile styling
• Widget quickhide button is annoying

Solution

• Make good mobile appstore ui

Testing

• Verify you can use the appstore on mobile without horrible size issues
• Verify no quickhide widget button anymore, but you can hide them from widget settings as before
• Verify small-screen widgets resize text correctly

Notes

As stated in #414, chess and settings apps Cargo.tomls had merge conflicts committed in them a while ago, went ahead and removed those as well.
