Show install log as part of installer instead popup window

[piotrzarzycki21]

Original request as reported by Justin,

Should we have the install log be a console so it displays what is happening, instead of the "install log" button? If we do make it more like a console, the user can see what is happening and there is one less button for them to press. Note that we should still have a copy to clipboard button, or even a way to view the location of the install log TXT file (which we should save automatically if we are not currently doing so)
