Syndicate Wars HD: Unguided campaign first level WIP

I decided to polish up the first level of the Unguided campaign. This was an early pre-alpha level, so missing a lot of niceties of more modern game levels, and actually was likely based on an old version of the Eurocorp second mission. As such I added some details from the final game missions based on the same idea, as well as a little cut scene and lots of other details.
