Subject: Allow more than one author, as required by specification
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Fatompub.git;a=commitdiff_plain;h=ee2d7dfb4a703544abbe9d0769f064aa1deaa383

Allow more than one author, as required by specification

The Atom RFC allows more than one author, which we didn't. Now, an entry
have an array of authors, which can be added to or retrieved. The header
also had the wrong function names.
