IoC properties support inside the repository - RIFE

To make IoC even handier, IoC properties support has been added to the Repository.

This means that you can do:

<!DOCTYPE rep SYSTEM "/dtd/rep.dtd">
<rep>
    <property name="datasource"><datasource>postgresql</datasource>

    <participant param="rep/datasources.xml">ParticipantDatasources</participant>
    <participant param="rep/scheduler.xml" name="scheduler">ParticipantMemoryScheduler</participant>
    <participant param="rep/site.xml">ParticipantSite</participant>
</rep>
