#482 Show Last Path enhancement

[Trevor Croft]

Dracorat:
Whenever a token is moved, the path it took would
remain visible on the board until the NEXT token is
moved. If the same token is moved again (not a
different one) then the path should be extended.

In the right click would be an option to clear the
shown path in case it got crazy (like if you moved the
pogs because of a teleport).
