Photo to Poster Pro versions

v1.8 [Mar 5, 2013]
* Fixed occasional crash when "No Frame" button is pressed. This issue only affected a very small number of users.
* Minimal screen resolution requirement downsized to 1024x768 and hence supports smaller screens such as MacBook 13". Users with larger screens are not affected by this change.
* Minor adjustment of layout.
* Removed unused Sandbox Entitlements.
