Updating logic and features to better match VT26

Updates include:

* Allow acticating tablets with hammer
* Remove 1/4 magic from the normal mode pool
* Incorporate OHKO compatible cape/cane-of-byrna requirements
* Upgrade Mirror Shield, Progressive Shield, and Bug Catching Net to
qualify as advancement items
* Allow Mirror shield as alternative to cape/byrna for Laser Bridge
* Prevent Waterfall Fairy from upgrading Boomerang or Shield
* Change PoD key logic to match VT26.
* Add restrictions on small key placement (to match VT26). I think these
restrictions may be redundant, but I'm adding them just in case any of
them are not.
