Description

Ask the user about its credentials, then download all the pieces of a GOG.com game, checking their integrity using the provided MD5 hashes.

Parameters:
- 1: GOG ID of game (like the last component of its gamecard URL)
- (optional: --alternate BASENAME BASEINDEX)
- (optional: --patch)
- (optional: --bonus)
- 2..: lowercase MD5 hash of each piece

Specifying --alternate allows to download a secondary installer for the same game (example: Alone in the Dark 2 and 3 are secondary installers for Alone in the Dark)
Default BASENAME: setup_<GOG ID>
Default BASEINDEX: 0

Specify --patch for game updates URLs
Specify --bonus for bonus contents URLs

Some hashes can be an empty string ("") to disable hash checking (not recommended).

Pieces will be named BASENAME.exe, BASENAME-1.bin, BASENAME-2.bin, etc. and the function assigns $POL_GoG_location with the full path of the first piece.
