This patch removes the concept of currentTarget and currentTask from the
BuildEvents code. To facilitate this I have moved logging to the task
level which now passes a task pointer to the project's log method.

Task level logging may also allow for more fine grained control of logging
in the future.

I have left the Project's log methods public to allow people's custom
tasks to continue to work. In the future these can become private.

extend Task or have any ideea that Ant will use them.

The only requirement is to have a
   void execute() throws Exception

That allows Tomcat ( and other projects) to define normal Beans and still
be able to script them.

The usage is identical with normal Task-extending Beans.

Also fixed bootstrap.sh.
