- changed access to member variable directly in CommandCell run instead of using getter (run() needs to be as fast as possible)
- null check added for missing cmd and missing URL on UrlCommand - alerts the programmer on save
- removed unused code
- changed proxy server to use http.proxy.host http.proxy.port
- had to temporarily comment a URL test due to a public server down
- restored test case that was commented out.
Handle cmd.getUrl() and cmd.getValue() on urlCommandCells
