Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.

+ *
+ *  Dual LUN Mass Storage demonstration application. This gives a simple
+ *  reference application for implementing a multiple LUN USB Mass Storage
+ *  device using the basic USB UFI drivers in all modern OSes (i.e. no
+ *  special drivers required).
+ *  
+ *  On startup the system will automatically enumerate and function as an
+ *  external mass storage device with two LUNs (seperate disks) which may
+ *  be formatted and used in the same manner as commercial USB Mass Storage
+ *  devices.
+ *  	
+ *  You will need to format the mass storage drives upon first run of this
+ *  demonstration - as the device acts only as a data block transport between
+ *  the host and the storage media, it does not matter what file system is used,
+ *  as the data interpretation is performed by the host and not the USB device.
+ *  
+ *  This demo is not restricted to only two LUNs; by changing the TOTAL_LUNS
+ *  value in MassStorageDualLUN.h, any number of LUNs can be used (from 1 to
+ *  255), with each LUN being allocated an equal portion of the available
+ *  Dataflash memory.
+ *
+ *  \section SSec_Options Project Options
+ *
+ *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.

+ *    <td><b>Location:</b></td>
+ *    <td><b>Description:</b></td>
+ *   </tr>
+ *   <tr>
+ *    <td>TOTAL_LUNS</td>
+ *    <td>MassStorage.h</td>
+ *    <td>Total number of Logical Units (drives) in the device. The total device capacity is shared equally between each drive
+ *        - this can be set to any positive non-zero amount.</td>
+ *   </tr>
