Give more details when an archive cannot be opened and give a warning instead of a crash

[Mimigris]

Player platform:

Windows, 64 bits continuous build of the Player.

Describe the issue in detail and how to reproduce it:

When trying to open a password-protected zip in the Player, a generic error message is displayed "Error loading RPG_RT.ldb" and forces the Player to shutdown. This may cause the player to be confused due to how vague the error is, and would probably be better to have more details and rather give a warning instead of an error when trying to open it.

Archive example: 12th_2459(PASS=VIPRPG).zip

Note that a similar scenario will happen if the compression used is not supported.
