Added port to config

[SeppPenner]

Summary of the changes (in less than 80 chars)

• Adds a configuration option to the BaGet server to specify the port it runs on, check appsettings.json --> Port.

Fixes #485.

The only thing to check here is that I don't know how to get the configuration in program without building the host twice:

BaGet/src/BaGet/Program.cs

Line 43 in 167fc22

// Todo: Don't know how to get the options without rebuilding the host!

This looks great! I left some nitpicks, but after that I think it's ready to merge :)

Now it looks good (and pretty clean) I would say. Sorry for the big amount of commits here but it's a lot easier to change one thing by one commit to not forget anything...

This probably addressed #289 as well (Can be closed, too after merge).

Yup this looks great. Thanks for the awesome contribution!

No worries, I squash commits when I merge changes, so feel free to do as many commits as you'd like.
