Set all forms to screen center position.
Added new combobox + logic for RuleType enum in Entities.Rule. The purpose is to separate file and folder sorting rules. A value is now stored also in the mappings file separated with a '#'.
Bug in the new ruletype combobox fixed.
Removed FoldersFolder. Replaced it with target folder.
Deleted the old folder sorting logic. Replaced it with the existing file sorting logic.
Added an unknown folders list in Entities.Mapping.
Unknown folders and files lists will get an added object whenever a file or folder has 0 rules that applies.
Refactoring.
Sorting is still untested in actual scenarios...
