* Update Electron dependencies
This will break some mods and a few things were deprecated, but the
Electron wrapper will be replaced anyway.
* Add macOS and arm64 packaging tasks
As @chunkybanana has tested the general approach to building shapez on
macOS, I can now add these tasks. Aside from that, now there are tasks
to build for the 64-bit ARM variant of each system and a task that
builds packages for all platforms and architectures at once. A bug where
localConfig wasn't created when building for the first time was also
fixed.
* Remove ad support, analytics and Wegame leftovers
The game may be somewhat broken in a few places, but it doesn't matter
for now. This is still not the end.
* Remove Steam SSO and demo stuff
Steam SSO is completely removed, a few things from demo like simplified
level sets are gone as well. Puzzle DLC on the other hand is now always
"owned" and will ask for a token to log in.
Removes
* Use shapez dialogs for Puzzle DLC token input
Yes, this sucks *a lot*. But it's a temporary measure, trust me :P
* Simplify HTML tasks
Removes the web (demo) index.html page and makes HTML tasks independent
of the build variant. This might not be the best solution, but it works
for now.
* Unify the version source
Changes the development config to use version from package.json and
makes the production config use the same utility function. Also removes
the version file as it's no longer needed.
* Remove some Steam references from build process
Removes files needed to publish the game on Steam and related tasks that
can be only used by the developer anyway. Only the build process is
affected, the actual game part still supports Steam integration.
* Refactor/add packaging tasks
Adds new Gulp tasks to create a distributable package of the game. A
task for macOS is not provided because signing needs to be figured out
first. Package creation tasks are also aliased in package.json for
future usage in external tools or CI. Aside from that, alternative
methods of downloading the libGDX Texture Packer are dropped.
