#19 Doxygen Logging

[Steven E. Schveighoffer]

Currently, with version 1.4, using ant -v does not
display anything with the doxygen task. In addition,
any failures that occur during the execution of doxygen
are silently ignored. For example, if doxygen fails
because it can't find the footer file specified, it prints an
error and exits. To the user who just ran ant, they
get "BUILD SUCCESSFUL" and no documentation.

The enhancements I believe should be added are:

1. when verbose mode is enabled, display all output from
doxygen

2. parse the output stream from doxygen from errors. If
an error occurs, throw a BuildException in ant, with the
error message as its string.

I'd also like to see the ability to specify a parameter that
allows the warnings (when things aren't commented properly)
to be seen.

ant -v would be a good start, but that will generate tons of
extra output during a build, when what we really want to see
is the warnings.
