LangFlags is expected to be less than 0x500 or whatever, zero indexed to
the start of the dex block; NOT an absolute position.
I don't feel like making every usage consistent (gen5, gui editors)
which use the absolute position, so just adjust in the zukan
constructors
Update comments / xmldoc
Add a savefile storage compressor (ie array[] with empty interstitials
-> list); return true if the compression moved anything (repopulate
views), and the count of occupied slots in the list.
Add saveblock base class; I haven't really liked how SAV6/7 do all the
logic; I'll still expose properties that will then point to a saveblock.
Cuts down clutter.
Add template Dex manipulator, with gen6/7 implementations
Speculate sequential gp/ge gameversion IDs
