Updated gog-back for new GOG site and fixed some issues

[alendit]

Hi,

GOG.com is all fancy and AJAX now, so the old gog-backup script didn't work anymore. I updated some parts (mainly login and manifest) and fixed Issues #1, #2 and #4 while I was at it.

Take a look, would love, if it where included in your repo.
