UPDATE!
Updating multiple installs is now actually working. i did silly and messed a bit of it up, so it basically did nothing. it is working now though. also, when a starmade update comes out, instead of waiting until you want to update, then downloading and installing it, to make things easier for my head, when starlaunch launches, it will check for an update. if found, it will download it without prompting the user, with a nice little download bar in the corner of the screen. this will not interfere with starlaunch in anyway, and will continue to run if starmade gets launched until the download is completed, and it will close itself.
