Some objects, notably PMTs can produce non-UTF-8 strings when
their __str__() method is called. For instance
>>> str(pmt.init_u8vector(1, [203]))
'#[\udccb]'
These kinds of strings eventually give a UnicodeEncodeError, for
instance when calling print() or displaying them with GTK. Python3
strings are supposed to be valid UTF-8.
When these objects are used inside block parameters in GRC, it will
produce several tracebacks and hang up. This commit fixes the problem
by sanitizing the strings to convert them to valid UTF-8. The sanitization
uses the 'backslashreplace' error response from Python.
Issue #3398 is caused by this problem.

All of the removed `from __future__ import` were needed in older
versions of Python (mostly 2.5.x and below) but later became mandatory
in most versions of Python 3 hence are not necessary anymore.
More specifically, according to __future__.py[1]:
- unicode_literals is part of Python since versions 2.6.0 and 3.0.0;
- print_function is part of Python since versions 2.6.0 and 3.0.0;
- absolute_import is part of Python since versions 2.5.0 and 3.0.0;
- division is part of Python since versions 2.2.0 and 3.0.0;
Get rid of those unnecessary imports to slightly clean up the codebase.

This commit adds a new parameter type to GNURadio Companion that allows
you to select directories using a gui. This functionality is
very similar to that of the previously available "file_open" and
"file_save" parameter types, and mainly differs by calling GTKs file
chooser with FileChooserAction.SELECT_FOLDER.
