v0.2 - Shardship The Mercantile

As the game starts with Shardship The Mercantile, it only feels fitting to name this release after it.

New in this release:

• Add support for keeping your downloaded files with the key "keep_downloads" in game.json. By default this is set to false, but by putting it on "true" the launcher will not delete these files.
• Add support for launching the game. Once the update loop is finished, the launcher will now by default launch the game. This behaviour can be changed by setting the "no_launch" key in game.json to true, after which the launcher will simply shut down.

Bug fixes:

• After doing a clean install, the launcher would skip doing updates.
