Added instructions on how to work from behind proxy

Windows build instructions do not work if you are behind a proxy
or have a Temp directory that you do not own directly.

+likely match this pattern: <code>http[s]://[username[:password]@]somehost.com[:port]</code>.

+<p><b>Warning:</b> If you are running Vista or Windows 7, Cygwin may have trouble with implementing <code>fork</code>
+(the POSIX function frequently used to start child processes, needed by many of the WebKit build tools).
+In order to enable <code>cygwin1.dll</code> to implement fork successfully it is better if no DLL loaded in the parent process is relocated at runtime.
+One way to achive this is to rebase all cygwin dlls except <code>cyglsa64.dll</code> and <code>cygwin1.dll</code> to base addresses that cause them to not overlap in memory.
+<p>In order to rebase all cygwin dlls a <code>rebaseall</code> script is provided in the cygwin installation's <code>bin</code> directory
+(usually <code>C:\cygwin\bin</code>).
+This script must be run from <code>ash.exe</code> (found in the same directory) while no other cygwin application is running.<br>
+<code>ash.exe</code> has very limited command line editing features so cutting and pasting to the commandline is recommended.<br>
+The <code>PATH</code> environment variable may not contain the <code>/bin</code> directory by default
+thus the script should be launched as <code>/bin/rebaseall</code>.<br>
+If <code>rebaseall</code> is complaining about failure to write to a Windows Temp directory (i.e. <code>/cygdrive/c/Users/you/AppData/Local/Temp</code>),
+fix the permissions on that folder (i.e. <code>/bin/chown you /cygdrive/c/Users/you/AppData/Local/Temp</code>) or
+change the TMP environment variable to point to a directory with the appropriate permission flags (i.e.: <code>export TMP=/tmp</code>).
+<p><b>Note:</b> The rebase process may need to be repeated to include any new libraries added later to cygwin by listing these libraries by full cygwin path in a file 
+and passing the file to <code>rebaseall</code> via the <code>-T fileName</code> commandline argument.
+The dlls under <code>LayoutTests/http/conf</code> are a relevant use case.</p>

+<p>If you are behind a proxy you need to do the following to allow cygwin svn to get through the proxy (similar steps are available for your Windows svn):
