1. Added two new functions, oilsIDL_links and oilsIDL_fields.  They
return pointers to the links oar fields hash of the IDL, respectively,
for a specified class.  They do not use oilsIDLFindPath() or any form
of strtok().

2. Applied the new oilsIDL_fields function in oilsIDL_ntop()
and oilsIDl_pton().

3. Applied the new oilsIDOL_links function to a couple of spots
in oils_cstore.c, to avoid the inefficient oilsIDLFindPath function.

4. Eliminated a couple of unnecessary lookups for class names that
are already in hand.
