Upgrade to 1.8

I just upgraded to dasBlog 1.8. The main reason was that the texteditor (ftb) in version 1.7 didn't work with IE7.

For those looking to upgrade to 1.8: the page editentry.aspx produces an error when you use IIS on Vista. The error I got was:

   "System.ArgumentException: Item has already been added. 
   Key in dictionary: 'ꆈꌠꁱꂷ (ꍏꉸꏓꂱꇭꉼꇩ)' Key being added: 'አማርኛ (ኢትዮጵያ)' "

The code asssumes that the name of the culture is unique. I vaguely remember an article on changes to the way cultures work in .NET; those changes could be the reason this assumption is not longer valid.
