removed unused imports, local variables, and private methods
(still there, just commented out).

default mode (inherited behaviour from JDT).

- added xweavedir attribute for weaving from and to
a directory of classes

- copies resources by default when using the Javac adapter
- does not copy resources unless specified when invoked via AjcTask
- copies injar resources always

Also adding warning for resource-copying (36071; copyInJars, sourceRootCopyFilter)
I would like to disable entirely, but don't see and haven't gotten confirmation of behavior from last week's telephone call.

- permitting fork in incremental mode only when using tag file
- pulling aspectjtools also from the task classpath
also failonerror default was not true as stated in the docs

These would break only when running from a Javac compiler adapter and using <compilerarg>

- findToolsJar now accepts versioned jars
- supporting a forkclasspath to permit user  to explicitly set
- upgrades for testing
  - so multiple iterations work,
    - not altering cmd in execute() 
    - only fixing up outjar once
    - reset() complete 
  - so incremental compile tests work,
    - passing quit through to main

- when forking on windows, use javaw rather than java 
  if possible to avoid popping up a console window

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

- noWeave has correct case
- better handling of list arguments
- better comments
- still largely untested

and tries to work around javac source-pruning operations, with only limited success.

-  forking
- compiler adapter delegation
- bootclasspath, extdirs, by putting on classpath (weak)

- normalized path support for all path-like elements
- reorganized for readability

Currently showing VerifyError on recompile -- need to investigate further.
