[FEATURE] Env file

[darkspadez]

.env file support

Currently bakery_hub and bakery are hard coded requiring manual intervention when forking. This allows for a .env file to override those values for better fork support.

I use -s as this will only source if file is there and is not empty.

How to use

Move .env.example to .env and update bakery and bakery_hub values and build.

This all stems from #135

@t-lo Here is environment file support!

Nice work, thank you! This should really be helpful for local testing. Could you please also update README.md and call out the env file in the "host your own bakery" section? Might also be worth mentioning that people would need to git add --force it if they wish to maintain a long-term fork as it's in .gitignore.
