added some new methods, exportToolPortfolio which connects the tools export url via httpUrlConnection. Currently having problems getting this to work. may be due to the security stuff (it works on the older versions before the security changes and hibernate 3 changes) Will fix this!
The basic activity creation method wasn't setting the activity type, so the isBlah() calls were failing. Also fixed (hopefully) the LearnerProgress relationships so that we always get the true activity object, not a proxy.
