v0.17.0

Original game bug fixes:

• Fix F12 key not responding after first keypress. Thanks to @SuperSajuuk for reporting this.
• Fixed ship textures randomly reverting to point instead of bilinear filtering, causing them to look pixelated.
• Mission 17 no longer reduces the available texture memory pool for ships, and they should display at full detail.

New features:

• Add new Direct3D9 renderer.
