Poccil's Tilemap Rewrite

BUMP
To version 1.3

Someone told me that the checkerboard pattern taken care of within version 1.2 for RPGMaker XP users still existed for users of kyonides's HiddenChest executable. I believe that it involves the way HiddenChest handles the actual Sprite class (not RPG::Sprite). In fact, I would suggest that HiddenChest's handling of sprites is an improvement of RPGMaker XP's.

The issue involves a necessary minor increase in zoom applied to priority flagged tiles. Without the increase, zoomed tiles may appear spaced apart upon completion. However, the increase in zoom is not required as much with users of HiddenChest.

As a result, I added one more configurable value that lets one adjust the zoom increase. And the instructions for that value suggests default values for both default RPGMaker XP and HiddenChest.
