Non ascii characters in path

[Matthieu Berthomé]

When saving gcode to a path that contains non ascii characters, I get this:

Traceback (most recent call last): File "C:\Program Files (x86)\JetBrains\PyCharm 2016.3\helpers\pydev_pydevd_bundle\pydevd_exec.py", line 3, in Exec exec exp in global_vars, local_vars File "<input>", line 1, in <module> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 46: ordinal not in range(128)

We can convert the value given by QtGui.QFileDialog.getSaveFileName to solve that. I'll send a PR

I suspect this is duplicate of #138.

Yes it is, I should have searched before :-)
