expose total item count + paginationUrl helper

[drudge]

I have a need to get the total item count for display while paging. I've exposed it as itemCount.

Additionally, I created a paginationUrl helper that is passed to the views to allow constructing URLs properly when baseUrl already contains a query string.

@tonymilne any interest in merging this? If not, I'll publish a new module to npm.

+1 for this. I was just looking to see if I could get hold of the total count...
