Adress issue vecs/fiji#62

Due to the weird level mechanism of Log4Perl the we cannot (easily)
set the verbosity directly but only increase it. Rename functions and
variables to reflect this better and use the new function correctly.

Since the appender is defined in logger.conf and thus loaded by all

but the CLI EE tool.

Move code from FIJITestsViewer and generify it to make it usable for
other modules like the EE CLI tool.

Use it to launch the documentation in fiji_setup
