[FEATURE] Add title-based ignore list for windows

Float windows automatically based on the window title, similar to the functionality provided by the class and process ignore lists. This feature is something I would like to make my current setup work: Godot and my external editor tiled, but the game debug window floating. I can't use the existing functionality since both windows have the same process and class. This was already requested in #200, but it seems it did not get any response. There is also another similar issue #83, but this PR might not fully solve that use-case. I implemented the feature by extending the IWindowMatcher framework with ByTitleMatcher class and TitleIgnoreList property, following the pattern used for the already existing exclusion types.
