Reorganize folder structure to match Vue idioms

• Move icons + sounds out of src into assets
• Move App.vue, main.css directly under src
• Reorganize JS files into store, utils directly under src

@sebastianovide did I break anything in the PWA/Android app?

did I break anything in the PWA/Android app?

yep. something happened to the heading: TypeError: myLocation.sstHeading is not a function

[steinbro]

Grr, typo. How about now? Maybe next I'll convert to TypeScript to catch those at compile time :)

[sebastianovide]

yep, +1 for TypeScript ....

I don't see the errors any more but I cannot see the arrow neither...

[steinbro]

I don't see the errors any more but I cannot see the arrow neither...

Yeah, noticed that too, filed as #40.

Do you see the arrow on the currently deployed site? I'm concerned this was an earlier regression not related to this PR.

[sebastianovide]

neither... It did happened before...

[steinbro]

OK, try this branch again.

I think there were at least two bugs I introduced that broke the compass on both iOS and everywhere else. The permissions issue in #40 was due to my turning the active mode setting into a Vue reactive variable and moving this logic into a watch handler instead of leaving it in the click handler where it apparently needs to be.
