Mostly cleanup.
Minor additions & updates:

• Maintain and show software version, currently 2.5.
• Cleanup sloppiness in bash scripts.
• Added a flavicon.ico.

NOTE: Browsers might still complain about using a self-signed certificate for Calvin, the simulated CA. If that happens, you have the option to simply push past this by accepting the certificate. But, better to fix things up front, IMO.

Worked for me with Firefox and Google in Linux:

• Clear the browser cache and cookies.
• In the location window, set: https://{IP Address}:{Port} where {IP Address} matches the subjectAltName in bin/diyca_web_cert.cfg and {Port} matches the PORT variable in app_web/diyca_web.cfg.
