Add dependency on logback and configure logger to log to
~/.runelite/logs/application.log with rolling file appender, that means
every 10MB file will be rolled and also every day file will be rolled
with maximum history of 30 days, to not flood user's system space.
Add new console parameter -debug, because logback properties cannot be
set from console like slf4j-simple ones, so it needs to be done in a bit
more complicated way.
