20. Support relative catalog paths

Configuration on Java
-
Property file property
relative-catalogs

Configuration on .NET
-
Property file property
relativeCatalogs
If relative-catalogs is true, relative filenames in the
catalogs
property list will be made absolute relative to the current working
directory; otherwise they will be made
absolute with respect to the base URI of the properties file from
which they came.
This setting has no effect on catalogs loaded from the
xml.catalogs.files system property which are always made absolute
with respect to the current working directory.
