With this thcrap is able to look for updates without depending on the repository and pick different URLs depending on information stored on its update server.
Now a PROJECT_BRANCH property is globally available, allowing for different versions of thcrap to be created and maintained differently without having to modify thcrap_update.dll;
Instead of cycling through every patch.js stored in the repository searching for the highest "thcrap_version_min", it tries to download a json ("thcrap_update.js") from one of its update servers.
thcrap_update.js contains a "branch" object, and every branch object contains its latest version number, the path to download the latest version, plus a list of optional milestones, which have to be downloaded before every other update (an example is available here);
Failing to download thcrap_update.js generates an error similar to the ones triggered when an update fails. Multiple consequential error of this type will be suppressed while still logging;
config.js is now globally available and is accessible through accessors that handle type conversions and errors. Every change is immediately persisted (different processes/instances may generate unintended behavior. This isn't really a new problem, but it's something to keep in mind).
