Offset

[harkus]

Due to the prevalence of static navigation, it's pretty much a requirement that an offset should be added to the scrollTop feature as such:
add to line 17: offset : 0
modify line 192: scrollTop: $('#spidochetube_player').offset().top - settings.offset

I'm not sure if pagination needs any tweaks.

Docs should mention the new feature so calling spidochetube({}) can include offset: int
