Mojang has changed its manifest format for 1.13.
Forge is no longer a universal jar, it requires more hosted files, all of which are generated by the installer.
We can no longer extract the version manifest from forge's jar and have to include it in the distribution.
This commit adds support for launching forge only, mods are currently not supported from the distribution.
Handling of 1.13 launches are subject to change as we move forward.
Fixed bug which prevented mods with declared extensions in their identifiers from being loaded.
Synced distribution.json with remote.
Updated electron-builder.
Updated readme to include information on beta testing.
Removed the version from the module's name. The version can be retrieved
from the identifier and placed wherever desired.
Reorganized the modules to have the more popular/important mods listed
first. The order in which modules are declared is the order they appear
on the UI.
Updated the docs to make it clear that maven identifiers are required for
all modules not of type File.
Added distromanager.js to represent distro elements.
Moved all distro refresh code to distromanager.js.
Overhauled assetexec.js.
Overhauled handling of assetexec.js output in landing.js.
Overhauled events emitted by assetguard.js.
Improved doenload processing in assetguard.
Updated discord-rpc to v3.0.0.
Replaced westeroscraft.json with distribution.json.
Use npm in travis for windows + linux.
Remove file extension from imports.
Added liteloader + macromod + shaders to distribution.json.
