Improved the decoding of OID search ranges in AgentX dissector:

1/ OID highlighting on first OID of a range was too long.
   The code incorrectly used the length of the printable string instead of the
length of the source data.
2/ Added bitwise dissection of the 'include' field of an OID decoding.
3/ Added corrected 'start/end' range information to SearchRange decoding to
discriminate between an 'end' indicator (old way) and the new way that shows
both an inclusive/exclusive indicator as well as a start/end range indicator. 
(applicable to getnext/getbulk requests.  (get requests are shown with 'less
noisy' decoding.

Patch file and sample capture included.
