Fix palette issue in 16bit mode, while setting the first colour to black.

Treat some default properties in set_model_ex, if the new model has some un-initialized values, just copy them form old entity data.
There's not a more efficient way to check all properties by now.

Don't change entity's direction if it is running.

Truncate fillcolor value if in 8bit mode.
shadowalpha is changeable through script.

Don't reset stalltime if it is player type.

Adjust risetime when model is changed.
TODO: copy the data instead of change directly in model.

Default risetime for players, if it is not set by the modder. This will keep old mod like before.
Also aggression is default to 0 now.

Reset the stalltime if an entity walk against border or wall.

Fix a bug that the enemy will grab a player forever without attacking.

Fix background offset-y, it should look same as in old time.
