[brownie scripts] UI ecosystem request

[BlinkyStitt]

I have started to pull my Brownie scripts out of my private repos and put them into a git repo dedicated to Rarity. This will make it easy for other people to install them and use Python to automate their summoners.

I already have some scripts working, but they haven't yet been copied into my repo.

• [ ] summon multiple
• [x] generate random ability scores (related #55)
• [ ] set skills for multiple summoners
• [x] level up multiple summoners
• [x] adventure for xp
• [x] scout and adventure on any contract
• [ ] craft multiple things
• [ ] manage a Guild and any NPCs (See #57)
• [ ] create a Dungeon (see #58)
• [ ] buy a name

These scripts use multiple smart contracts to manage the summoners.

There are a few utility contracts that are probably useful for everyone:

• CloneFactory: I know gas efficiency isn't as important on Fantom compared to ETH, but this is pretty easy to use and makes contract deployments even cheaper.
• DelegateGuard: revert if (or if not) delegate called
• RarityCommon: contract addresses and approval helpers (related #15).
