Map: World of Symmetry

[Omnirizon]

i think 155 and 172 supposed to be connected. fixed.

also, fixed mispellings (symmetry not symetry) and out-dated name references (v0.3 still referencing a tga file called symetry2 from when map was v0.2. unless the tga file has ever been changed, it shouldn't even have version update. map file now simply references 'worldofsymmetry' to make this more obvious.
