Support for filters in PropertyConfigurator

[avielfedida]

From the docs[https://logging.apache.org/log4cxx/latest_stable/classlog4cxx_1_1PropertyConfigurator.html]:
"
The PropertyConfigurator does not handle the advanced configuration features supported by the DOMConfigurator such as support for Filters, custom ErrorHandlers, nested appenders such as the AsyncAppender, etc.
"
Did anyone added or attempted to add support for filter when using PropertyConfigurator and a properties file such as
...
log4j.appender..filter.=Custom or built in filter
log4j.appender..filter..param1=X
log4j.appender..filter..param2=Y
...

this does not work and is unlikely to be added at this point, since filters can be rather complicated and not easy to configure in a properties-like configuration. You are welcome to try and add support, but it would be less work to simply convert your configuration file to XML rather than try to use properties.
