[PATCH] python: Make Results have a nicer __repr__.

[Tobias Mueller]

* lang/python/gpg/results.py (Result.__str__): Renamed to '__repr__' ...
* lang/python/gpg/results.py (Result.__repr__): ... and added fields
--

So that it looks a bit nicer in the Python REPL.

It looked like this before:

In [2]: gpg.core.get_engine_info()[0]
Out[2]:
<gpg.results.EngineInfo at 0x7fb23509a240>

Now the output is

In [2]: gpg.core.get_engine_info()[0]
Out[2]:
EngineInfo(file_name='/usr/bin/gpg2', home_dir=None,
protocol=0, req_version='1.4.0', version='2.1.11')

This also applies to other results, e.g. the ImportResult.

Note that the format now changed from "<Class >" to "Class()". The
Python documentation on repr states: "For many object types, including
most builtins, eval(repr(obj)) == obj."
