Path glob to mapper files

[matheusca]

Hi!

Organize my mapping files I separate mapping in many files that makes sense for me. So I created a main mapping file that it got all path, as following:

Lotus::Model.configure do
  adapter type: :sql, ...

  mapping 'mapping/users'
  mapping 'mapping/tasks'
  mapping 'mapping/scheduled'
end

It works very well, but it more redundancy for each mapping I will need putting these files in main mapping file.

My suggestion if will be possible use a glob path in main file. For instance, my file could be more elegant as following:

Lotus::Model.configure do
  adapter type: :sql, ...

  mapping 'mapping/*'
end

I saw that it is not possible at the moment, because the Config::Model(https://github.com/lotus/model/blob/master/lib/lotus/model/config/mapper.rb#L34) try get a realpath.

If guys agree with me, I will implement it refactoring the code.

I like the idea to separate in several files the mapping, because in big applications the mapping will be big.

what do you think @lotus/core-team ?

@AlfonsoUceda I do like this idea too, I even think that having lib/bookshelf/mappers as a conventional placeholder. Thoughts?

On second look, doing multiple mapping does not work correctly in the current version, the latter one would override the one before that. So the PR should also handle that first.

As of v0.7.0 we don't support global mapping anymore.
