[Po4a-devel]0.17.1 in the pipe, please update translations

Hello, I'd like to release 0.17.1 since it's full of good fixes in it. Indeed, I would have released 2 or 3 dot releases in the process, but I kept refraining myself from releasing something without letting you update your translations, and fuzzying the strings at the same time... So, let's say we're in string freeze (to break the cycles), and that we're gonna release as soon as the [binary] translations are uptodate. Thanks for your time, and sorry for the fuzzy ;) Mt. -- C combines the power of assembler with the portability of assembler.
