Spiritus Astrum [P0-B12]: p1513: Towards Early Access

I have created some simple textures for the new vehicles and weapons that I have introduced for the new campaign.

I have also integrated these into unity and tested the new weapon models. There were some minor bugs that needed to be fixed, but nothing major.

There is a decent selection of different weapon types that are unlocked at different points in the campaign.

I have also improved the mounting code for the weapons to give the player additional choices regarding their weapon loadout.

The next goal it to continue adding art for the new campaign, as well as testing, debugging, etc.
