Lackey

* Merged Sikuli shim into Lackey main code

* Implemented pyramid matcher to improve image search efficiency

* Implemented the rest of the main Sikuli classes, including `App`, `Settings`, and `Debug`

* Fixed 14 TypeError on doubleClick()

* Fixed 5 bad region validation
* Fixed 7 findAll() listiterator error
* Fixed 9 _convert_sikuli_wildcards should be a class method
* Fixed 10 Region.below(), Region.right() getScreen error
* Fixed 11 clipRegionToScreen() errors
* Fixed 12 memory leak

* Added multi-monitor support (Screen() class should be fully functional and Sikuli-compatible, except for interactive functions)
* Moved `capture()` method to `Screen` class instead of `Region` (where it had incorrectly been placed)
* Screen class now properly inherits Region
* Added lastMatch shortcut for click()
* Implemented raster functions for Region
