[Plugin: Rotating Posts] Creating a default thumbnail, truncating title

Hi all.

I just made a couple of posts on my site relating to two issues I had and resolved:

Creating a default thumbnail (if you forget to add a value for rp_thumbnail custom field)

Truncating the title text (as this pushes the post text down and messes up alignments)

Not super huge things, but annoying things I had to modify code to get going. Hopefully this can help someone else if they run across these issues.
