Categorized exclusions

[spriadka]

Short description of what this resolves:

This PR implements the possibility to manually exclude test classes/methods from execution based on their category (see #310 )

Changes proposed in this pull request:

• added the excludedCategories into the categorized configuration
• changed the AbstractParser logic to support this feature
• added the CategorizedTestSelection which serves as an information holder to the categorized selection, which then transforms to the TestSelection using the toTestSelection() method.

Hi @spriadka thanks for your contribution and sorry for my long inactivity - I was knocked out by flu in last 8 days. I'll do the review today.

Thanks for the feedback @MatousJobanek . Sorry for my long inactivity as well, I was not able to make until yesterday. I made some major changes e.g removed group imports, changed test logic, removed the CategorizedTestSelection class etc. However, I would like to stand by the IncludingCategoryFilter and ExcludingCategoryFilter as it seems more elegant way than passing a boolean parameter into a method.
