Remove devutil/__init__.py

It only provided a single function, `printable_node`, for printing XmlNode
objects. These are not really used in Picard anymore since the switch to the
JSON web service.

-def printable_node(node, indent=0):
-    """
-    Print a XmlNode so output can used in test scripts
-
-    Useful to debug mbxml.py mostly and to create unit tests using "real" nodes.
-
-    Example of usage:
-
-        from picard.util.devutil import printable_node
-        from picard import log
-
-        def _translate_artist_node(node):
-            log.debug(printable_node(node))
-            ...
-
-    will output to debug log something like:
