Merge lp:~zeitgeist/zeitgeist/fix-909708 into lp:~zeitgeist/zeitgeist/bluebird

[Seif Lotfy]

This branch fixes the issue where inserting and event with 2 subjects.
Since we already parse the subjects before insertion I added a list with subj_uris to find if there is a duplicate and return 0 if one is found

[Siegfried Gevatter (rainct)]

 - Why do you use a List? Make that a SList. Even better, we know how many subjects there are so we can just use a fixed size array or something.

 - Fix the formatting: "null) {", ".append(s".

 - A comment before the "return 0" explaining what happened would be nice ("// Events with two subjects with the same URI are not supported."). Also, return a warning so people will notice they're doing it wrong.
