[rules-users] rules files character encoding and sprint patch

[Joachim Van der Auwera]

Could one of the drools developers look at JBRULES-3633 and the pull 
request in there?
It would help me a lot if this patch could be applied. Please let me 
know if there is any problem with this patch, I will improve it as 
needed. We have been using a patched version for a while here without 
problems.

The issue allows users to specify the character encoding to be used to 
read a rule file when setting up your knowledge base using spring 
configuration.

Thanks,
Joachim
