SCBlock doesn't have an absolute index; it was only used for tagging in dumps. Offset and Length weren't used.
Removing these 2 ints from the SCBlock object reduces alloc req by 8 bytes each; if we have 2,500 blocks in a save file, this reduces the memory footprint of a sav by 20KB. Nice side effect :D
Remove block dump comment from accessor; new logic in Meta8 for dumping DLC sizes does the same logic with less hassle.
Apparently my copypaste of the class didn't delete all the old unused controls. Ha!
Move non-gui logic to core as separate classes, in case ppl wanted to reuse them in their own projects.
