ignore DSL inside ignore.ghiqc

[h1alexbel]

Let's add support for special syntax in order to configure tool to ignore some issues. For instance the following ignore rules can be placed in ignore.ghiqc:

author:jeff
!author:foo
author:(jeff|foo|max)
!author:(jeff|foo|max)
label:foo
label:!bug
title:"bar"
title:"*foo"
title:!"*something"

We can add author:unknown too. In case bug report was submitted by newcomer, it will check the issue, otherwise no checks will be performed.

Main quality problem: Lack of clear explanation on what the bug does.

Suggestion: Provide more information on what the bug achieves and how the specific syntax works.
