Issue #1 Fix

This is my proposed fix for issue #1. I replaced start.sh with a start.py that allows specification of the wavsep install.jsp parameters, as well as alternate HTTP and AJP13 port numbers. I also altered the README significantly to explain invoking the script: https://github.com/dwvisser/pico-wavsep/blob/enhance/README.md
This seems to be unnecessary, why re-configure it again?
It should be configured with the first call, and then just used. WAVSEP will store the configuration somewhere, if the user wants to re-run the configuration he should run the command with any of the `--mysql*` configuration flags
