Allow to use page URL in pagination pattern.

Browse source 
Currently it was only possible to use page "save as" name or part of it
for generating pagination links. That's not sufficient when page URLs
differ a lot from actual filenames. With this patch it's possible to use
the `{url}` placeholder in PAGINATION_PATTERNS setting. For example, the
paginated archives would be saved to:

    blog/index.html
    blog/2/index.html
    blog/3/index.html

while the actual URLs would be like this (with the help of Apache's
mod_rewrite):

    http://blog.my.site/
    http://blog.my.site/2/
    http://blog.my.site/3/

The configuration that corresponds to this is roughly the following:

    ARCHIVES_SAVE_AS = 'blog/index.html'
    ARCHIVES_URL = 'http://blog.my.site/'
    PAGINATION_PATTERNS = [
        (1, '/{url}', '{base_name}/index.html'),
        (2, '/{url}{number}/', '{base_name}/{number}/index.html')
    ]

Also added YEAR_ARCHIVE_URL, MONTH_ARCHIVE_URL and DAY_ARCHIVE_URL
settings, as they were missing and now they make sense.
