Use static final Patterns in XMLElement

[merks]

• In o.e.pde.internal.genericeditor.target.extension.model.xml.XMLElement there are a number (5) of string constants that are compiled for each XMLELement instance that is created that could all instead be compiled once and recorded as static final variables.
• Also the patterns used to computer isStartElement and isEndElement don't properly handle line breaks, i.e., don't handle \r, and are better compiled using Pattern.DOT_ALL.
