Support for Surround SCM history

I added support for Surround SCM history.

Just started running the code on our project which includes thousands of source files and a lot of history.  Seems to be working well so far.

I am using it on Window 7 with Glassfish.

Pre-requisites:

sscm.exe must be on path and must be able to access Surround SCM server without requiring username, password, server and port.
