module-folder-structure: add fix capability

[flaviostutz]

When a "simple" folder structure is required, "fix" creates those folders.

Example:

{
  "rules": {
    "module-folder-structure": {
      "strict": false,
      "folders": [
        "src",
        "libs/**/release"
      ]
    }
  }
}

In case a module has no folders in it:

• Folder "src" would be created (it will fix the problem)
• Folder "libs" would be created to indicate the "direction" of the structure (but won't fix the problem, which is ok)

In case a module has folder "src" and "libs/mylib":

• Folder "libs/mylib/release" is created (it will fix the problem)

The overall idea with the rules is to iteratively work with the dev, in the loop. It shows an issue, the dev fix something, it fixes another and shows new issues on and on... until all is fixed. This will be nice specially when we have our VSCode plugin #12

@sergioflores-j @tiagostutz what do you think?
