Install.dev.py updates

• It would be nice to have a "Would you like to install with all defaults" option at the start of the install script so not to have to press enter lots of times. If you say, "No", then you can press enter where you want defaults, but then enter different variables (much as you have now) if needed.
• Could we have it so there is an option during install to either install or not install Word press? Default should be to not install.
• Could we have a "Installed in xxx mins:sec" final output so we can compair times?

I've implemented your first point

The user is given an option to press y to skip manual variable assignment. Pressing n will cause the script to run as normal. This does not affect any other warnings, such as overriding files.

I've implemented your latter point

The timer displays at the end of the installation script when successful
