version 2.2 released

There were some bugs found in previous versions, and a number of other enhancements found in this release.

Also, all of the system calls are now implemented, and you may play with them as you see fit. It will allow you to request more space for memory if you like.

I aim to have text highlighting working by the next version, and a bunch of other little goodies.

Thank you,
Tim.

P.S. The branch is not quite as feature complete as the trunk, but all of the new features will be migrated to it as time progresses. This is because of the way that its coding structure differs from the trunk, and not laziness.
