Adds the E-2C Hawkeye to the game. (#714)

* Adds the E-2C Hawkeye to the game.

It wasn't being imported from pydcs, and thus wasn't in the list of AWACS aircraft or prices.

Also adds it to the 1985 US Navy list, as that makes sense to do.

Updates .gitignore to ignore my VS Code settings file.

Addresses Khopa/dcs_liberation#709
