Unicode path save/loading

[Angus Yeh]

Loading of 'current directory' seems to fail when the path name contains strange characters (eg. the degree superscript circle in this case).

see ui_main_window.py, loadSettings(), wd = str(s.value("current_directory", "").toString()).

I might be able to try/except here. But maybe there is a better way to support unicode or things like that?

Fix Issue #84 of failed to load strange path, now fail safe whole settings loading.

TODO: improve the setting loading and inform user what's wrong. Or even solve the unicode path issue.
