70 add fuel tokens (#71)

* updated design document. * onchain with fuel tokens. * fixed shipyard unit tests. * offchain for creating ship with fuel tokens. * moving ship with fuel tokens. * gathering fuel tokens. * burning remaining fuel tokens when mining asteria. * burning remaining fuel tokens when quitting. * creating pellets with fuel tokens. * removed burn of fuel check when admin consumes pellets. * consuming pellets with fuel tokens. * refactored unit tests. * WIP: fuel policy tests * removed vscode settings file. * fuel policy tests * fixed name * updated plutus.json * updated script refs * fixed typo. * minting no tokens check on GatherFuel redeemer. * updated spacetime script ref.
