allow setting homepage and bugtracker in minil.toml

[icklekitten]

Minilla assumes I want to use github as bug tracker and homepage in META.json.

I don't.

Maybe there is already an option for this, but I cannot find it in documentation or source code.

patches welcome.

Should be pretty easy for me to write patch.

Forked project and installed dependencies but a lot of the test cases fail. Mostly it's this error:

You need to set user.email in git config.

But I did set user.email in git config already.

Oh, works if I use --global for config.
