[EP-tech] Error in XML::LibXML

Dear all,
after the XML::LibXML module upgrade, to 2.0201 released on Jan, 13, eprints crash, complaining that it can't process anymore entities in XML phrases files. 

Example of error:
---
Failed to parse XML file: [phrase_file.xml]: Entity: line 9: parser error : Entity 'agrave' not defined 
---
After 2 hours of debugging, with two sites down ( :-( ), i realised that with this version the module needs one more MANDATORY option at startup, that enables external DTD parsing, now disabled by default. 
This patch is for 3.3.15, but it's so simple that i think it works also in 3.4.* ...
