modifying option setting to make that test pass

Class.forName differences between IBM and SUN's JDKs

- split classpath
- check for array arguments

added narrower knownLimitation test

assert or <name>.class in the body

the fix for now is just to not inline such advice, but in the future these
should be transformed to inlinable constructs

Bugzilla Bug 37020  
   wrong line for method execution join point
(but points to first executable line rather than method declaration)

and

Bugzilla Bug 37021  
   source path wrong in declare warning on binary files

between IBM and SUN's JDKs -- not yet tested on IBMs JDK to confirm

between IBM and SUN's JDKs

Moved a nit-picking part of SourceLocationWithExpr to its own test that
is listed as a known limitation.

- better toString for logging message lists

include the stack trace as tooltip text if there
is an associated exception

- if a source line message contains a throwable
and the user double-clicks, this displays the error dialog
that permits them to copy the trace.  That should mean that
multiple exceptions can be in the task list.

- closing streams to permit better test cleanup

- buildStructure test API now builds everything
- removed unused code from pre-IMessage days

- handling new fast-fail config errors
- better error display, no messages lost

Implemented new options merging:
- can specify any local config file options

- project properties and build options
  now can contain any options and 
  override local values only if not set

- have method to fixup the options for IDE's
  to enforce their invariants, but this needs
  to delegate to a new adapted API.

- broadened size and meaning of "non-standard compiler options" to "other compiler options"

and commented out one test because it does not add the file correctly (to a matching task)

longer has a bin dir. Updated the classpath to include
jdtcore-for-aspectj.jar instead.

- usage printed once by caller
- any arg mistake is an error
    (i.e., not ignoring/continuing)
    (does not include list entries like classpath)
- refactored commands to share common error-handling code

- !! changed warnings to errors, so now
  not compiling after command-line mistakes
