Incorporates files from #190
Skeleton added for future implementations; currently missing gifts,
encounter info, and the fine tuning that follows.
Basically sets up areas for future implementation... feel free to submit
pull requests filling in the EncounterStatic/EncounterTrade blocks with
the basic info. I'll probably focus on gen5->4->3 in terms of priority.
Encounter slots need to be marked up for encounter slot legality (yay
32bit RNG), and will be used for PIDIV detection too.
XD/C is not in this round of implementation. Pretty much every pkm 3-5
will show up as invalid until this round of dev is finished.
changes IV3 to faster variant used elsewhere,
sort properties alphabetically,
simplify 'any' intersection,
un-duplicate database filtering
un-duplicate box/folder per-pkm processing
-25 lines, a little bit of reorganization since the form has grown since
its initial inception
use last char of file extension if available. edge case for pk[m]
considered:
pk[m] => 0x6D, -0x30 = 61d, &7 = 5, which prefers 6 instead of 7+ :)
adds a check for transferred pkm not having their CurrentHandler being
flagged as the save file (impossible for a transferred PKM to be still
handled by the OT).
Move System.Drawing usage out of Core to WinForms, as System.Drawing is
not in .NET Core/Standard. Simple methods to return resource name
strings have been added instead.
