First crack at supporting 3 Fortify report types: xml, fvdl, fpr
Fixed bug when parsing FVDL files
Parse a ZIP file entry without loading all its data into memory
consolidate xml file open
Merge remote-tracking branch 'origin/master' into feature_import_fortify_fvdl
Moving Fortify code to use BaseImporter
merge in master
Check for audit.fvdl file size before opening from .fpr ZIP

Used defusedxml for parsing xml
Move common xml parsing code to a BaseXMLImporter class
WebInspect uses the BaseXMLImporter
