Move static docs into master branch

The hand-maintained static HTML docs for DevStack have been in a
GitHub gh-pages branch; move them into the master branch in
preparation for hosting them in openstack.org infrastructure.

By default tools/build_docs.sh now builds the static HTML output
into docs/html.

+        
+        <h3>Hardware</h3>
+        <p>This guide covers the creation of a bootable USB drive.  Your 
+           computer BIOS must support booting from USB and You will want at least 3GB of 
+           RAM.  You also will need a USB drive of at least 2GB.</p>
+
+        <h3>Software</h3>
+        <p>Ubuntu 11.10 (Oneiric Ocelot) is required on host to create images.</p>
+      </section>
+
+      <section id="installation">

+        </div>
+
+        <h3>Set Up USB Drive</h3>
+        <ul>
+          <li>Insert the USB drive into the computer.  Make a note of the device name, such as 
+          <code>sdb</code>. Do not mount the device.</li>
+          <li>Install the boot system:
+            <pre>tools/build_usb_boot.sh /dev/sdb1</pre>
+            <p>This calls tools/build_ramdisk.sh to create a 2GB ramdisk 
+               containing a complete development Oneiric OS plus the 
+               OpenStack code checkouts.  It then writes a syslinux boot sector
+               to the specified device and creates <code>/syslinux</code>.</p>
+          </li>
+          <li>If desired, you may now mount the device:
+            <pre>mount /dev/sdb1 /mnt/tmp
+# foo
+umount /mnt/tmp</pre>
+          </li>
+        </ul>
