update macros.add()
proper compiler output delimiter in the stdin compiler service
nimrod dump can now produce a machine readable json report

The data in the report includes necessary information for starting
the compiler service and setting up the project paths in the IDE.

the default verbosity of 1 is now set in the compiler code to fix an
issue with verbosity being temporary set to 1 during config parsing
even when it's explicitly overridden on the command-line.

compiler/lexbase was temporary renamed to nimlexbase as a
work-around for a codegen naming conflict with lib/pure/lexbase
resulting in linking errors (further investigation needed).
Changed babel path handling.
