Ignoring unknown attribute Bug

[Mew2K]

Issue Description: Similar to issue #20, attempting to load this map causes these warnings to be thrown to the console. Like issue #20, the map fails to even load. The reason I separated this into a separate issue is because this map throws warnings regarding "Ignoring unknown attribute", whereas the map in issue #20 does not. NOTE: After further inspection, it seems both Block Runner maps throw these warnings about unknown attributes even in 1.8 PGM, though I figured I would still post this issue just so it's documented.

Map: Block Runner: World of Sports

Version: PGM-0.16-SNAPSHOT-3c8fd1f9.jar
