L3DT v2.2a release announcement

This revision to L3DT 2.2 is largely a 'look-and-feel' upgrade to make L3DT easier to use - particularly for new users. The main changes include:

• Addition of the next button in the toolbar, so that you don't have to remember the right sequence of menu options.
• Progress bars now have 'cancel' buttons, as well as time estimates for most calculations (via multithreading).
• There's now a delete water body mouse tool.
• The mouse cursor is now mode-dependent (FINALLY!).

If you experience any problems with this release, please tell me so.
