Release Notes:

Details:
drawview:
- if image isn't loaded yet (complete-flag isn't set), drawImage() needs 
to defered, cf. 
"http://www.whatwg.org/specs/web-apps/current-work/#dom-context-2d-drawimage"
- also added a check to protect against invalid an image-argument
- and changed getImage() to save an image under the resource-name and 
the load url in order to prevent resource-images to be loaded over and 
over again

LzSprite:
- getResourceUrls():
o moved all code which changes sprite-properties out of the function
o added a note that the function is used in drawview
