This is for #123

@dejan Any chance I can get this into the mainline?

[gogiel]

Due to recent changes this PR is no longer valid. @mikeweaver are you interested in fixing it?

[mikeweaver]

Yes, I'm interested in fixing it...if it gets merged to the mainline this time around. Two years gathering dust taxes one's motivation. :-)

[gogiel]

Great to hear from you :)
I have a collaborator status. Once you update the PR I'll be able to review and merge to master.

However I can't guarantee the due date for a new gem version release as it's beyond my capabilities.

Thanks.

@gogiel I rebased my changes onto the latest master and have a green build. Should be good to merge. LMK if I missed something.

[modosc]

@gogiel i can get this gem released once it's merged, just ping me.

@mikeweaver thanks! I see that you're introducing new concept of config YAML files.
How about using currently existing solution of configuration block?

I believe that configuration in Ruby code is more flexible and simple.
We can add YAML config too but it should be consistent with all existing config options.

Please rebase master again. I reverted accidentally removed code in Config, #160
