Bugfix Update & Server Browser

Good afternoon all!

A bunch of changes in today's update, mainly focused on ease of entry for anyone who purchases the game in the future and wants to play without getting into a server.

Now, the default "Play" option in the menu will spawn you into a solo roam map, let you roam around, collect weapons, items, etc, fight snakes, and generally get a feel for the game.

In addition, the server browser has been fixed, so now anyone who wants to host their own server can, and it will appear in the in-game server browser.
