New HTTP Plugin filter; fixes.

The Grinder 3.0-beta29
----------------------

  Nested Tests are supported. That is, you can now use a Test to
  instrument script code that calls things wrapped by other Tests.

  A __target__ field has been added to test proxy wrappers, allowing
  convenient access to the wrapped object.

  New implementation of the HTTPPlugin TCPProxy filter. Key new
  features over the previous filter (which is deprecated):
   - Records to a single script.
   - Basic Authorization is recorded.
   - Modular implementation based on an XSLT style sheet.
   - Requests are grouped together into pages, using simple rules that
     guess the resources belonging to a page based on the resource type.
     Pages are instrumented as separate tests.
   - Name value tokens are identified in URL path parameters and query
     strings and mapped to script variables. Most session tokens that
     encoded in URLs or present in hidden form fields will now be
     handled automatically.

  Several changes to the script API, including:
    net.grinder.plugin.http.HTTPRequest:
     - Removed addHeader(), deleteHeader()
     - Header arrays passed to GET, POST, etc. are now merged with the
       default values held by the HTTPRequest. Previously they setting
       an array on the request overrode all the default values.

    net.grinder.plugininterface.PluginThreadContext:
     - getStartTime(), startTimedSection(), stopTimedSection() have
       been replaced with pauseClock(), resumeClock() to support nested
       tests. (Since now there can be multiple active dispatch contexts).

    net.grinder.script.Statistics:
     - Query methods now return meaningful results within wrapped code.
     - Added getStatisticsIndexMap. Thanks to Beecher Greenman for
       reporting this omission.

    net.grinder.plugin.http.HTTPUtilities
     - New class. This has methods that HTTP scripts might find useful.

  The HTTPClient Authorization module is no longer enabled by default
  because it prevents raw Authorization headers being sent through.
  The module also slows things down as HTTPClient must parse responses
  for challenges. Advanced users who still wish to use the HTTPClient
  Authorization module can enable it with the new
  HTTPPluginConnection.setUseAuthorizationModule() method. The
  following convenience wrappers around the HTTPClient API were also
  removed: addBasicAuthorization(), removeBasicAuthorization(),
  addDigestAuthorization(), removeDigestAuthorization().

  The worker process to console communication has been made more
  efficient, and a race condition which caused "Ignoring unknown test"
  messages has been removed. Thanks to Dhinakar K for the report.

  The Grinder can now optionally use J2SE 5 System.nanoTime() which
  might give more precision on some platforms. Times are still
  reported in milliseconds. See the grinder.useNanoTime property.
  Thanks to Tom Barnes for requesting this feature.

  Fix console file scanning to used the same filtering as the file
  distributon. Thanks to whoever reported this. (Bug 1447361).

  The HTTP proxy code in the TCPProxy has been improved; this should
  address problems seen when chaining TCPProxy's together as HTTPS
  proxies. Thanks to Justin Nowell for prompting me to look at this.
