Dynamic tileset type 1

[Inverness]

All NW files have "GLEVNW01" as a header.

Stefan can just make a new format with "GLEVNW02" that would indicate that the level file is in the newer format.

That way none of the old levels would be broken.

Of course then Stefan has to be willing to update the level editor and all that other good stuff to support the new format if he chooses to add it.

GLEVNW02
BOARD 0 0 10 0 "1,45,235,5325,533,2,42,4,25,535,324"
BOARD 0 1 10 0 "1,45,44,234,124,2345,2314,123,123,412"
BOARD 0 2 10 0 "34,4223,200,200,200,200,200,200,200,45"
BOARD 0 3 10 0 "34,4223,200:7,45"

Example of new board format (not to full size obviously) where an array of tile numbers are used. In the last line one of the entries is 200:7 meaning that 200 appears 7 times, making it identical to the line above it. A simple compression technique.
