[development] low hanging fruit for Drupal 6: variable defaults

Quoting Moshe Weitzman <weitzman at tejasa.com>:

I didn't think of this when responding to Gabor but here is another what if:

We make the second argument optional and if not supplied we use the 
constant DEFAULT__MY_VARIABLE and if both are missing the variable name 
is used.  This gives Gabor a key to use to translate the text and it 
gives others a smoother transition after six years of using 
variable_get.
