MTGO Library Bot 5.70 is out

The lastest update of ML Bot, version 5.70, includes a number of small fixes. Notably, 5.70 fixes a problem with 'making all cards tradable', a problem partially fixed in the previous versions of the bot but still showing problems with particular collections.

ML Bot 5.70 implements also a more reliable connection with the server, resulting in a more stable behavior and less frequent messages like 'ml bot is unable to connect to the server, please wait'
