MxDSAction/Chunk/MediaAction/Sound (#85)

* Match MxDSChunk ctor/dtor

* Push work on MxDSAction/MediaAction/Sound

* MxDSMediaAction constructor is matching up to a mov location

* Match MxDSSound constructor by adding the missing member

just four bytes in between them in ghidra.. isn't that enough for ghidra to justify a member variable?

* Match MxDSMediaAction constructor

Today's lesson: ecx suggests '1'
