Changes

In order to build Mozilla from source you must create a build environment, incluidng [http://ftp.mozilla.org/pub/mozilla.org/mozilla/libraries/win32/MozillaBuildSetup-1.1.exe Mozilla Build (1.1 or newer)] and MSVC 8. Once both of these have been installed (they should already be in the lab), you only need to run '''Mozillastart-Build MSVC 8msvc8.bat''' (there is a link on the desktop) to begin (i.e., you shouldn't need to install anything).
