0.8.4 Hotfix

This is a incremental update that adds a couple things I didn't have the bandwidth to add for the earlier release, and addresses a few outstanding issues that needed to get adjusted before I work on the 0.8.5 milestone.

NOTABLE CHANGES:

- Adjusted menus to make them easier to navigate. Most changes are under the hood, but when using a gamepad you shouldn't get "stuck" in the menus as much. Also increased the visibility of the focused button and redid some colors to make certain features stand out.

- Updated the research base to use Elegant Crow's new models! They are great additions that I didn't commission soon enough for the 0.8.4 original release.

- Tweaked the terrain rendering and level of detail to increase performance with very little loss of quality

- Adjusted the storm effects on each helicopter to be more fun (read: not a tornado of fury) and added some subtle wind to the rain weather condition.

- Added an in-game button to join the Discord server from the main menu. Join us and make the game better!

Please re-download the EXE in it's entirety, this is not a patch but a full export. Thanks for the support!
