Error happens when transfer to a unicode language

[Cryspia]

When chooses Japanese, Simplified Chinese or Traditional Chinese in the Language menu, there will be an error logged in the terminal:

Traceback (most recent call last):
  File "freeseer\frontend\qtcommon\FreeseerApp.py", line 146, in translate
    self.retranslate()
  File "freeseer\frontend\record\record.py", line 227, in retranslate
    self.idleString))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

The problem is caused by not using unicode for .format:

            self.mainWidget.statusLabel.setText("{} {} --- {} ".format(self.freeSpaceString,
                                                                       get_free_space(self.config.videodir),
                                                                       self.idleString))

should be

            self.mainWidget.statusLabel.setText(u"{} {} --- {} ".format(self.freeSpaceString,
                                                                       get_free_space(self.config.videodir),
                                                                       self.idleString))

There are several places with the same problem in record.py

This fix will only work on certain versions of Python (which is fine for now, but creates an extra task if we ever support a version between 2.7 and 3.3).

Would it be better to use a suggestion from https://docs.python.org/2/howto/pyporting.html#from-future-import-unicode-literals?

IMO u'foobar' is fine because Python 3.4 is already the latest stable 3+ version and there would be no reason for a distro to ship anything lower once they make the transition to 3.

[dideler]

If we can port immediately to 3.4 or higher, then we're good. I'll go ahead and merge #585.

Issue still present for the avWidget (config tool). The PR only had fixes for mainWidget.

OK. I will also fix this one in this week.
