* - java runtime
* - normal process (good research, past figboot :3)
* - libraries
* - check which libraries we actually need (some have classifiers that don't apply to us)
* - of the libraries we need, check which have correct size and sha1
* - redownload necessary libraries
* - (if offline mode and there are libraries to download, then explode violently)
* - extract natives
* - logging
* - download the config if present and necessary
* - (explode if offline mode and we need to download stuff)
* - assets
* - get asset index (check if our local copy is good and redownload if not)
* - check what ones are good and what needs to be downloaded
* - download them
* - (if offline mode, explode)
* - if virtual or resource-mapped, copy (or perhaps hardlink? that would be cool)
* - the actual client jar
* - check integriddy and download if needed
* - (explode if offline mode)
* - launch the game
* - build argument list and whatnot also
