And rearrange files to work with the new layout for the finalized upgrader

Upgrader revisited

Reviewed-By: Jared Hancock

The upgrader can't (and shouldn't) do everything necessary to complete an
upgrade. The adminsitrator will need to take care of a few extra tasks that
are outlined in the UPGRADING.txt file. One of the items includes removing
source code no longer used in the 1.7 codebase. A script is shipped (Unix
only) that allows an administrator to automatically clean up all old source
files that are no longer used.

* Append page url to error alerts - useful in determining which page triggered the error.

Allow to upgrader to roll through tasks during upgrade without bread (trusting the tasks to break)

And remove unnecessary parts of bootstrap.css
