Adding new configuration-option "organize-versions"

[SchulteMarkus]

This PR introduces an new configuration-option "organize-versions", which can be set to "year" or "year_and_month". If set, the versions-classes (files) will be in appropriate sub-directories relative to "migrations-directory". For example, if you set "organize-versions" to "year" in your doctrine-migration configuration, and generate a new version, the new file will be placed in migrations-directory/2015/ (if the actual year is 2015).

This change is use-case-driven. When using doctrine-migration, having every version (98 by now) in the "migrations-directory" became ugly.

On the way, I removed unused "GlobFinder", which was unused and was not able to find versions in "migrations-directory"-subdirectories, as RecursiveRegexFinder does.

@SchulteMarkus Thanks for your PR but, you are trying to do way to many things at the same time and it become really hard to review your change. There are a lot of indentation and documentation fix all over the place which is great but should be in their own PR.

I am not removing the GlobFinder before the 1.0 of doctrine migrations (hopefully in a week or so).

You don't explain what your code is supposed to do which also makes it harder for me to review.

Can you please provide more information ?

Thanks

@mikeSimonson, I am reducing the PR to the new configuration-option "organize-versions", on Wednesday or Thursday, hopefully. I will provide the additional code-changes (such as indentation, adding .editorconfig ...) in other PRs by time.
This PR needs GlobFinder to be removed, as described. If your are removing GlobFinder in the near future, PR could be merged afterwards (if it is fine for you on the other issues)?!

[mikeSimonson]

@SchulteMarkus Well I still don't know what your feature want to achieve and how I should be using it?

[SchulteMarkus]

@mikeSimonson I have updated the PR-description a bit. Better understandable now?

[mikeSimonson]

Okay, yes I get it now.
You should still leave the GlobFilter as it is there for compatibility reasons and for people that thus won't use this option.
And then maybe add a check (if possible) that if the organize-versions option is set and the GlobFilter too, then output an error.

[SchulteMarkus]

Closing here.
I will readd this PR later, from a "clean" branch (without indentation fixes etc) and with a clean branch-history.

[mikeSimonson]

ok.
Don't forget about it. I think that it would be really useful.
