Closes#1137
allows loading of tab separated value text file "savpaths.txt" which can
also be used to 'favorite' locations (ie, the program checks for
duplicate paths and only adds the first).
folder availability checked on form creation
shortcut: press ctrl-F on main window
Thanks @sora10pls !
Adds game selection subform for RSEFRLG/Memcard game selection
Backs up entire memory card instead of just gci when loading from
memcard
Reduce string usage (easier dialog translation if that ever happens)
Does the memory card store date last saved? Could be used to autodetect
the last saved game and load directly instead of selecting.
Prefer 32-bit is enabled, so there will be no functional difference from before, except that any of the assemblies can be referenced by a 64-bit process.
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.
bad settings files cause exceptions, silently delete them
move language init out of loadconfig (want it to happen regardless of
config errors, so load config value instead)
