Add parameter to ignore missing poDirectory

[GoogleCodeExporter]

When you use Maven POM inheritance and have a lot of sub-modules in a Maven
project, you usually do not want to configure the compiling of the PO files
in each sub-module separately, but configure it in a super POM that is
inherited in all modules. Unfortunately, if you have some modules that
contain PO files and some that don’t, this becomes hard as the
maven-gettext-plugin will fail to execute the dist task if the configured
poDirectory does not exist.

To facilitate this kind of project structure, it would be very useful to
have a parameter that defines whether to ignore the missing of the poDirectory.
