jsonpickle: Add a pluginmgr module

This is the JSONPluginMgr formerly in __init__.py.
Factor this out so that we can call encode()/decode()
from within the un/pickler.

{pickler,unpickler}: Use the new pluginmgr module

Solve the import dependency issue introduced when merging
the dict keys support in 84748ab3ef221d25883318e527263276c6efcd98.
Dictionaries with dict keys (and other objects) are now supported.

Also, do away with the need for a separate DICT_KEY entry in tags.py
by reusing the existing OBJECT tag.

Closes #5

jsonpickle: Add a 'make_refs' option to encode()

This allows callers to disable jsonpickle's inter-object
referencing.  Redundant copies of flattened objects are
returned when make_refs is True.

pickler: Fix failing tests

Some logic may have crossed which caused the make_refs branch to fail
its tests.  The reason was that _mkrefs() changed to return either
objects or reference objects, but one code path was still returning
`bool`, which was its original behavior.

The unpickable condition has now been folded into the make_refs
condition which decreases complexity and fixes the tests.

runtests.py: Fix sys.path handling

Prepend into sys.path so that the source repo is preferred over other
paths.  This avoids failing tests when jsonpickle is already installed
in the default site-packages directory.
