Minor documentation bugs

Hello,

I stumbled upon a couple of minor documentation bugs:

1. In the readme.txt file, you have the path to the block config as: admin/blocks/configure/month - it should be: admin/block/configure/month

2. On the configuration page, for "Maximum month links in block:", the help text is: "Enter a number to limit the number of months linked in the block, blank or "0" to list all months." This is incorrect - if you put "0" in the box, then no months are displayed.

Thanks,
