Title: Fixed calcTm so that  it doesn't raise an exception when using the breslauer method.   Also fixed a copy past error in the salt method settings.

Modified code to check for `value == None` instead of `not value` when verifying that the tm_methods dictionary returned a value. This was a problem because that value could be 0.

Fixed a similar issue with salt method specification.
Also fixed a copy-paste error.
