Add the ability to open wikis in the browser

[Epicpkmn11]

Currently press SELECT and if the app has one it'll quit UU and open the browser
I feel like it should be possible to launch the browser without quitting UU as you can launch it from the home menu while the app is running, but that wasn't working.

• Add an icon you can touch, probably by release notes is my first though, I'll try find a good one in the morning
• Maybe make SELECT not open it? I just did that for testing but it might be an alright key for it I guess
• Add a warning that this will quit UU unless we can figure out how to not quit UU
• Try fix it quitting UU
• Try fix the browser sometimes being unresponsive (might be fixed?)
• New problem: Fix being frozen on return from browser
• Fix missing last character on o3DS

I also added the ability for custom Themes in the latest commit through a Themes.json. Might want to change the Pull Request Description or so. ;P

Should just not put unrelated things into specific branches ;P

I think it'd be better to cherry-pick that commit over to master and just wait on this for the next release since it's being buggy but do the rest now since there's already several bug fixes worth doing a release for

This works now, the 3DS browser definitely struggles these days but GitHub wikis do work at least if a little glitched looking
