2.2 released

You weren't using macros, were you? Good, because they're gone. The
macro interface was kludgy anyway. Instead, the alias command now
supports multiple commands separated by semicolons. Well, it's really
the basic command interpreter that does this, it just wasn't working
entirely correctly before.

The "unfix" for bug 480 regards the auto-line-increment for setting a
line breakpoint. It was a nearly useless feature anyway, considering how
poorly it behaved in the presence of inner classes.

- All commands may have their arguments enclosed in quotes, either
  single or double quotes.
- Aliases may contain multiple commands, separated by semicolons.
- Removed macro support now that aliases can run multiple commands.
- Implemented #429: option to disable the automatic refresh of the
  classes tree panel. See the updated "Classes" help for details.
- Implemented #524: option (default is on) to hide the core classes
  in the classes tree panel. See the updated help for details.
- Unfixed bug #480: took away fix for bug 480 because it was causing
  more problems than it solved.
- Fixed bug #520: attach command was not checking for null or empty
  port number and share name values.
- Fixed bug #521: fixed Java parser wrapper so it finds the correct
  line of code for the beginning of classes.
- Fixed bug #522: log was missing notifications and occasionally
  not displaying messages to the messages panel.
