v1.5.6Bug fixes.
Tree loading improved & full load option added.
Ltext searching improved.
Max file save size option added: hardcoded limit is ~4GBs. If you save & it's over this, program will automatically save extra filename_#.dat where # = number.
Virtual->dat save added: loading virtual folder can now be converted to single *dat file within max file save limit.
Multi-*dat save added: will save multiple loaded *dats, for example load Region & save. All city files will be saved.
2ndary level saving added: for example, load exemplar->user visible name key, update/save. For any item that's in the current loaded dat, still need to save the dat itself. For anything else it'll automatically save dat.
DIRs: Refresh button added. No longer updated/added automatically except on file saving.
This will most likely be one of the last updates
