Bug 37405

When using the replacefilterfile attribute, it would be handy to be able to
specify what delimiter should be used. Unfortunately, someone here has already
created a good number of config files using the pattern  #property.name# so one
would have to first create the temporary property file argument to
replacefilterfile with the delimeters appended/prepended. I've made a simple
change that allows for an optional attribute (default value "@@") to do this
prepending/appending when retrieving the token from the set of properties loaded
from the replacefilterfile file.
This way, a property file could be used as is and allow the Replace task to
create the 'correct' pattern.
