NO MERGE Various minor typelib fixes

Minor things stumbled upon while reading the typekit.rb

Not completely sure about the "orogen_include"-fix 600da84ca1b708f9386668d964dc5289e41a5aba -- please have a thorough look at it as it changes (corrects) the metadata for a lot of projects. An `autoproj rebuild` finally succeeded (besides the usual ramifications...)

The rest shouldn't do much of a headache.
Fair enough ... Let's not cut hairs in half.
