ENH support connection to DCM4CHEE pacs which requires specification of

the peer ATTitle.

The following now works, for example:

$ ./CTK-build/bin/ctkDICOMDemoSCU 174.129.38.17  11112 MI2B2
I: Requesting Association
I: Association Accepted (Max Send PDV: 16340
Successfully sent DICOM Echo to host 174.129.38.17 on port 11112

which should correspond to:

echoscu 174.129.38.17 11112 -aec MI2B2

using dcmtk tools.
