Filters/ExactMatch: deprecate the getBlacklist() and getWhitelist() methods

Deprecate the `getBlacklist()` and `getWhitelist()` methods and introduce the `getDisallowedFiles()` and `getAllowedFiles()` replacement methods.

When available in child classes, the `getDisallowedFiles()` and `getAllowedFiles()` methods will take precedence over the deprecated `getBlacklist()` and `getWhitelist()` methods.

Fixes 198
