Linted the entire project. Using different rules for the script files
as there are a lot of undefined variables just because of the way the
DOM's global scope works.
Mostly just code cleanup, however the linter did catch a minor bug with
a settings regex. That has been corrected.
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.
Added option to enable/disable prerelease updates.
Implemented launcher tab on the settings UI, as this is the only current value.
Added semver dependency.
Major improvements to distribution index loading.
Implemented new transitional UI for startup.
If **no** distribution index is loaded on startup, completion of startup will be prevented and the user will be shown a message displaying the issue.
Launch errors are now shown as overlays.
Many more minor fixes and enhancements.
Separate views are stored in an ejs file. When the app starts, each file will be loaded, with the DOM elements hidden. Based on the state of the application, a specific view will be fadded in. Switching between views will use this principle.
Moved contents of index.ejs to landing.ejs to make it compatible with the new format. As a result, index.ejs is deprecated and will be removed once it is no longer needed for reference.
