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.
Where is #generate? You mean the hard-coded metadata [here](https://github.com/orocos-toolchain/orogen/blob/master/lib/orogen/orocos.tlb#L10)? The function would still recurse and include the header for its "of" type -- `uint_8`?
