fixed graphical bugs if digging or collecting caused player relocation

If digging or collecting (but not snapping!) certain tiles or elements
causes the player to be relocated ("teleported"), the corresponding
digging or collecting animation for this element will not be continued
anymore (because the player does not move towards this tile anymore).

To fix this problem, the digged or collected tile will be treated like
being snapped (using a temporary run-time element) for this edge case.
(The resulting engine behaviour is slightly different to the previous
behaviour, but should not break too many levels as this case should be
rather uncommon.)

This adds a new command "autofix" that can be used to test and try to
fix existing tapes (by setting a property bit in the tape header).

The only patch currently available is "em_random_bug" that sets the
property bit for using the 64-bit random value workaround in the EM
game engine (see commit 1006b2db for details).

good idea! :-)

fixed wrong eater content when loading native EM levels

This fixes a regression bug from commit baf962d5 that causes wrong
eater content when loading native EM levels.

Native Emerald Mine levels before version V5 only supported 28 eater
objects, but some levels contained object codes above that, which are
now mapped to empty space. (Before, they were mapped to the first 32
eater objects (28 objects, padded with four empty space objects) using
"mod 32" operation, which lead to completely wrong eater objects for
nearly all affected levels.)

Mapping these eater objects to empty space is the best solution for
now, as nearly all affected levels are solvable when using empty space
objects instead (as most of these objects originally mapped to doors
or letter elements).
