Add option in the controller config to set where static assets are
loaded from in order to support deployments where the static assets are
server via a CDN while the API is directly accessed.
This is useful because some CDNs put low limits on how large requests
bodies can be, which causes issues with uploading large mods and saves.
Catch uncaught errors and display the error message on the page itself
if bootstraping fails. This should prevent most cases of the of the web
interface being stuck on "Loading web interface..." after an error was
thrown and the loading failed.
These variables were intended to be globals declare in the global
namespace. That this ends up on the window object is an implementation
detail of JavaScript. Remove the window. prefix put in front of
staticRoot and webRoot and include the global declaration in the
TypeScript module.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
