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?
