OsWorkflow latest experience

Didn't look at OSWORKFLOW for a while, today's latest code, I found a lot of heart-moving changes:

1) The support for WebWork is stronger, but the version is a bit old, it is 1.x; I like 2.x2) support for Spring is also very strong Because WorkflowConfiguration can specify WorkflowFactory and WorkflowStore, so we can separate all profiles of OSWORKFLOW from Spring 3) Function also supports Spring configuration mode: SpringFunction 4) In addition, the Test Case of OsWorkflow has enhanced many, although it looks that Hani is not very like to write Unit Test. :)
