#111 — /archive/ hardcoded into weblog archive urls

by default the weblog_archive format is '', i.e. to reach the archive don't append anything to the blog's URL, go straight for the year:

/blog/2007/
blog/2007/09/ etc.

in those views the instantiated (year/month/day) archives have a correct absolute_url (which is used to create their clickable links) of /blog/2007 etc

this is, because we already specified the proper context via the /blog/2007 url

if, however we instantiate the archive without that specific context, i.e. in the archive portlet all of those archive objects get an absolute url of /blog/archive/2007 etc. (which leads to 404s)

ideally, the absolute_url methods of the archive's would take that configuration setting into account.

as temporary workaround i will set the default archive_format from '' to 'archive'. this way new installations' archive urls will always coincide with each other and there will be no nasty 404s.
