Make lyx_pot.py python3 compatible
Now it produces the same output if running under python3 (tested with 3.4.2) or python2 (tested with 2.7.9). python3 always uses unicode strings internally, so we have to specify the file encoding on opening a file, such that strings can be converted from and to the file encoding on reading and writing. Using the io module for file io ensures that the behaviour is the same for python2 and python3. For python2 we also have to mark string literals as unicode strings by using the u prefix (which is a noop in python3). Many thanks to José for review and pointing out all the details.
