Allow custom token replacement

[GoogleCodeExporter]

Could Roundhouse be extended to allow custom tokens to be supplied in the 
command line and used throughout?

I specifically have in mind being able to pass a login which the scripts can 
set as the owner of the objects being deployed.

Tokenizing this would let me supply a different login depending on the 
environment I am building against...Dev, UAT, Prod.

At the moment as a workaround I'll use the .ENV. convention but this will mean 
maintaining separate scripts for each environment, which differ only by the 
login ID they contain.

Thanks
