Store and display average hashrate (benchmark + on share)

Displayed data is the average of the last 50 scans in the 5 last minutes

Also move cuda common functions in a new file (cuda.cu)

 >>> RELEASE HISTORY <<<
 
   Nov. 11th 2014  v1.4.7
+                  Average hashrate (based on the 50 last scans)
                   Rewrite blake algo
                   Add the -i (gpu threads/intensity parameter)
                   Add some X11 optimisations based on sp_ commits
