as2-lib 4.4.7

• Simplified ICertificateFactory to work on IBaseMessage
• Fixed a missing HTTP header unification when using the async MDN (see #97)
• The async MDN is no longer send in a separate thread but in the main thread of the processor, so that retry etc. works
• Fixed too much quoting when having path values inside of the attributes pendingmdninfo and pendingmdn (see #97)

• ph-commons/ph-xml/ph-collection/ph-security/ph-datetime/ph-bc 9.3.7
