Change project owner to elementary and rename to Maps

[ryonakano]

Part of #110

I made the commit 0826b75 with the following commands:

$ git grep -l com.github.ryonakano.atlas | xargs sed -i "s/com.github.ryonakano.atlas/io.elementary.atlas/g"
$ git add .
$ git ls-files "*com.github.ryonakano.atlas*" | while read line; do mv $line ${line//com.github.ryonakano.atlas/io.elementary.atlas}; done
$ git add .

What would you think about io.elementary.maps to match generic names of other default apps?

[ryonakano]

Yeah I'm not opposed to that! Users would be more familiar with Maps rather than Atlas.

@danirabbit I no longer have administrative permission to this repository, would you rename this repository to "maps"?

[danirabbit]

@ryonakano you should have admin now! Otherwise I'll be back at my desk Monday 😅

Done!

Nice!
