Adding DTD's to the catalog

[Ross Gardler]

I need to add some documents that use a custom DTD to my project. As per 
the instructions at 
http://forrest.apache.org/docs/validation.html#catalog I have placed my 
DTD's in src/documentation/resources/schema and have a new project.xcat 
file (in the same directory).

If I run "forrest validate" all my docs are validated, however if I run 
"forrest site" the files with the new DTD's fail because Forrest is 
trying to download the schema from the web (and they are not there, only 
local).

Any ideas?
