Title: Use an empty ArrayList for each session being sychonsied

Fix for Issue #77 - Ensure a new ArrayList is used for each session feedback being synchronised.

(This could also be achieved by clearing the questions array list, but doing things this way allows the HTTP communication to the server to be offloaded to another Thread ad some point without any concerns about the object values being altered)
