Title: Fail hard when using multiblog and blog name is not specified

Previously all helpers would just default to "first blog" unless specified. This change causes Middleman to fail with an exception instead, forcing users to specify the blog in either the helper arguments or via frontmatter. Single-blog sites are unaffected. There essentially is no longer a concept of "default blog".

This aims to prevent the confusion from issue #166.
