EAn build 0.98 released

Thank you all for your patience. We are ready with this new build 0.98. The new features introduced in this build are:

-   Persistence. You can save your work in EAn for later load. Standard XML mechanism is used to persist the class model and object spaces information.
-   class methods (operations) support. EAn will now compile methods information (name, parameters, types). At this time there is only compile time method support, but soon it will be extended to run-time methos execution.
-   Help files synchronization
-   Minor fixes

For the next build (0.99) we are planning some major EAn clean-up. Some refactorings will be done, help and documentation quality will be improved and more integration with EA will be added.
