Fix for bug with 2 page pagination

[nitelite]

This line doesn't seem to work on albums with 2 pages. It picks up the "next page" link with a chevron in it for the last page and crashes since its not a number.

Line 84 in b7c3e73

last_page = int(pagination.find_all('a')[-2].text)

Suggested fix:

        page_links = [a for a in pagination.find_all('a') if a.text.isdigit()]
        last_page = int(page_links[-1].text) if page_links else current_page
