SRGSRC now accepts command line arguments

New command line argument:
-a <SRG DIRECTORY> <SRC DIRECTORY> (Automatically runs the tool with the
specified SRC and SRG directories)
-nogui (Disables the graphical interface for use with consoles, must be
used with -a)

EX: java -jar srgsrc.jar -a "C:\srg" "C:\src"
Added console mode without -a argument message.
