fix ant task documentation
integrate ant task documentation into main documentation
remove unused variable
fix cleanup of task variables
do not skip ant task execution if input and output have the same last modified date, as this most likely means the input and output files are identical and thus the timestamps are not good up-to-date check
fix NullPointerException in ant task when parameter or option are given without name
fix code-style issues
fix wrong error messages
fix output resource handling
remove unused variables and unnecessary assignments
fix method name
fix wrong JavaDoc comments
fix if attribute for Option and Param nested tags which were documented but not accepted and considered
use pipeline directly as Resource and let Ant do the conversion implicitly
honor failOnError setting for misconfigured pipeline elements
show a meaningful error if no pipeline is given instead of throwing a NullPointerException
also check whether libraries and pipeline are specified together and give a more meaningful error message than 'Unparseable option'
output a linebreak before the usage message to separate it from the error message and make that one more observable
fix, improve and extend the usage message
