corba/Convertions: add default-case for EnumType-conversion functions...

fixes a -Wunhandled-switch-case by adding the default.

hope i got all the places... jeeez...

also add some "'"s around the integer and enum-name and at an additional
place in "to_string" EnumType for easier reading.

add the now-needed include for "rtt/Logger.hpp" -- does it make sense to
use this as output-facility? not sure here...

sidenote: actually the whole enum-conversion does not more than catching
invalid values?

typekit: "metadata" does not have "include?", use "get" instead

the function could be actually added, in a quiet moment...

typekit.rb: add metadata "orogen_include" elementwise

am not a ruby expert. old way didn't work when more than one include was
returned. this works.

using "set" in the first place is problematic as it will overwrite
existing entries. using "add" instead.
