Open editor with prompt to open from options

[DamSenViet]

When user's open the editor they should be able to select from ACNL, ACNH, from Storage/Upload/Conversion instead of going straight to the editor in ACNL mode. This will make it much more clear that ACNL and ACNH are different format types.

At this prompt we can display an information tooltip to tell the user that there are different restrictions between the format types.
