PRERELEASE #3 OF TRADECLIENT 0.3.0

We've added LDAP support to TradeClient, so that it supports a global address book. The dynamic version is expecting to find the dynamic OpenLDAP libraries. Likewise, if you are compiling your own, OpenLDAP will be required to be installed. If you do not want LDAP support compiled in (you don't need the OpenLDAP libraries), edit the Makefile, and change "WANTLDAP=1" to "WANTLDAP=0".
