Ore stack size overridden when Dectorio gravel enabled

[dgw]

Dectorio optionally allows placing ores (coal, copper, iron, and stone) as floor tiles that look like gravel. Picker overrides ore stack sizes when that option is enabled, because ores gain a place_as_tile property that makes Picker think they're just like any other tile. By default, ore stacks are doubled from vanilla's 50 to Picker's default tile stack size of 100. (See jpanther/Dectorio#44)

While this can be worked around by setting picker-tile-stack to 50, that means the function isn't usable for other, non-ore tile types.

The fixes that occur to me are:

1. Simple option: Add a toggle to disable Picker's tile stack changing function. (I noticed it's not guarded by a setting.) This is essentially like setting the tile stack size to something small, because Picker will not decrease the stack size of a tile type, only increase.
2. More complicated option: Skip overriding the four ores Dectorio touches, since they're not tiles unless that mod is present.
3. Most complicated idea: Skip any ores, including ores added by other mods (Angel's, etc.)—probably not worth the effort, to be honest.

This option has been moved to picker tweaks mod for .16. Additionally setting the setting to a value of 0 will not change any stack sizes.
