Added Assembly to perform builds pushed out to sourceforge

Used existing builds to sourceforge to regenerate close to identical
build using assembly.  Only difference is the naming on the build
package.  It is close enough!

Removed old sample tomcat-logback.xml as no longer needed since assembly
builds this out.
Added license files for logback, slf4j, and tomcat
Added setenv.bat & setenv.sh
Added logback configuration files using parameter for days, sync'd days
between two files, performed tab to space formatting on file.
