Request to expanding the includes features

[MiguelAPerez]

Issue:
While using the available includes features some limitations were found when trying to exclude patterns (due to glob). For example when using ! on a character group, each letter is ignored instead of the group:

"include": [
        "sub-projects/![FooProject]*/composer.json"
],

This will exclude sub-project/F*, sub-project/o*, sub-project/o*, sub-project/P*, etc from being processed. This issue also causes significant toil when trying excluding multiple paths.

Proposed Solution:
To get around this and not change how includes works, I suggest implementing an excludes attribute. This attribute would array_diff on the includes and allow refined excludes patterns.

"include": [
        "sub-projects/*/composer.json"
],
"exclude": [
        "sub-projects/Foo*/composer.json"
],
