Migrate to dbus-next

[acrisci]

Migration to dbus-next (a fork of dbus-native) is a rewrite, but fixes
some outstanding bugs in the project related to variant types.

The project is now transpiled to use the experimental decorator feature
that will be available in the language at some later time. gulpfile.js
contains build instructions. Build with npm run build. The dist/
folder contains what will be published on npm.

Interfaces are implemented as classes with decorators specifying the
properties of the member that is exported on the bus.

Update examples and add a new tracklist example.

Other bugfixes may have been a side effect of the rewrite.

fixes #1
fixes #6
fixes #13

I do believe this works, but dbus-next is not released yet so you'll have to wait for that to merge. No breaking changes in the api were intended. I think it works, but it should be tested a bit more.

I've talked to @sidorares and he said he is interested in merging the service interface of dbus-next. So consider this a reference implementation.

Any news about this?

@emersion sorry still didn't have any free time, maybe over holiday period

No worries, and thanks for your hard work on dbus-native!

Sorry for the rewrites. Can't wait to finally close my stupid playerctl bug.

This would be absolutely awesome to have mpris-service based on node-dbus-next :D

The last problem to solve is to get my required node engine version down to about 6.3 and then I can go about my glorious mission to fix javascript media players.

Hey @emersion this is ready for review.

Run npm run build to build the project to the dist folder.

Run tests with npm run test (they may be flaky the first few runs, but then they become stable for some reason).

Build docs to the doc folder with npm run doc

There are still some TODOs, but I think it's better to merge this as-is. This LGTM.

Thanks for your hard work, that's quite impressive :)
