Need to allow make code coverage on nashorn project

Please check, correct if necessary and apply the attached diff (named cc.diff) to allow code coverage. Currently it supports only dynamic instrumentation.
Also diff contains a fix to allow redefine setting by local properties ${user.home}/.nashorn.project.local.properties (it needs to simplify automation execution of custom machines)
 
Code coverage is disabled by default
to enable it redefine in the ${user.home}/.nashorn.project.local.properties
parameter
make.code.coverage=true
and check that jcov2.lib.dir points to correct location (default value is upper directory of nashorn project - jcov2.lib.dir=${basedir}/../jcov2/lib)

redefine if necessary, like
jcov2.lib.dir=/opt/jcov2/lib
