Major plugin refactor and cleanup.

Switched to POCO library for unified platform/library interface.
Deprecated the external module API. It was creating more problems than solving.
Removed most built-in libraries in favor of system libraries for easier maintenance.
Cleaned and secured code with help from static analyzers.

+	/// The Attr interface represents an attribute in an Element object. Typically
+	/// the allowable values for the attribute are defined in a document type definition.
+	/// 
+	/// Attr objects inherit the Node interface, but since they are not actually
+	/// child nodes of the element they describe, the DOM does not consider them
+	/// part of the document tree. Thus, the Node attributes parentNode, previousSibling,
+	/// and nextSibling have a null value for Attr objects. The DOM takes the view
+	/// that attributes are properties of elements rather than having a separate
+	/// identity from the elements they are associated with; this should make it
+	/// more efficient to implement such features as default attributes associated
+	/// with all elements of a given type. Furthermore, Attr nodes may not be immediate
+	/// children of a DocumentFragment. However, they can be associated with Element
+	/// nodes contained within a DocumentFragment. In short, users and implementors
+	/// of the DOM need to be aware that Attr nodes have some things in common with
+	/// other objects inheriting the Node interface, but they also are quite distinct.
+	/// 
+	/// The attribute's effective value is determined as follows: if this attribute
+	/// has been explicitly assigned any value, that value is the attribute's effective
+	/// value; otherwise, if there is a declaration for this attribute, and that
+	/// declaration includes a default value, then that default value is the attribute's
+	/// effective value; otherwise, the attribute does not exist on this element
+	/// in the structure model until it has been explicitly added. Note that the
+	/// nodeValue attribute on the Attr instance can also be used to retrieve the
+	/// string version of the attribute's value(s).
+	/// 
+	/// In XML, where the value of an attribute can contain entity references, the
+	/// child nodes of the Attr node provide a representation in which entity references
+	/// are not expanded. These child nodes may be either Text or EntityReference
+	/// nodes. Because the attribute type may be unknown, there are no tokenized
