Add a helper function to reset a node's/item's color info

if a neutral node somehow ends up with different itemstack
meta when placed and then later dug.  Prevents look-alike stacks.

 If your node if of the kind where you need the split palette, but you need to put the *full color name* into the node name, as opposed to just the hue, then add the keys `ud_color_start` and `ud_color_end` and set them to the positions of the first and last characters of the color name (where 1 is the first character of the mod name at the start of the node name, i.e. "mymod:foo_bar_orange_baz" would have the start set to 15 and the end at 20).

 `airbrush_replacement_node`:  The node to swap in when the airbrush is used on this node.  For example, you could `minetest.override_item()` on some default node to add this field, pointing to a colorable node of your own, so that when the default node is painted, it's replaced with yours in the new color.

 This one does just what it sounds like - it shows the color selector formspec.
 
-**`unifieddyes.on_construct(pos)`**
-
-This function, usually called from your node definition's `on_construct`, just sets the `palette = "ext"` metadata key for the node after it's been placed. This can then be read in an LBM to determine if this node needs to be converted from the old 89-color palette to the extended 256-color palette. Although it is good practice to call this for any node that uses the 256-color palette, it isn't actually necessary as long as the node has never used the 89-color palette, and won't be subjected to an LBM that changes its color.
