Since we already generate the man pages automatically,
we can generate the bash completions too.
It is much faster and does not risk making any network requests.

fixes #194

TODO this is less efficient on python2

TODO: should be factorized

The user may now use conditions on durations (from the audio and the video
capabilities) in repl applications.

The documentation has been updated to take this change into account.

"sort" is confusing, we filter results, not order them. "sort out" would
also work.

autopep8 -a -r -i --select E711,E712,W601,W602,W603,W604,W690,E304,E401,E502 .
Also includes some manual reindentations (many are left after the print()
changes).
Manually checked, some modernizations not commited here.

python modernize.py --no-six -f libmodernize.fixes.fix_print -w

With manual fixes as the import was put always on top.

So people don't waste time altering them, but alter the source instead.

Python does not like """"

This reverts commit ff34cc7b.

This reverts commit fc9a503f.
It breaks manpage

autopep8 -i --select=W602
Also some other minor deprecated syntax changes, like "while 1".
I did not commit the less obvious changes.

This should fix the display of manpages with accents (mainly boobank).

This is recommended by Debian.
closes #618

I used autopep8 on some files and did carefully check the changes.
I ignored E501,E302,E231,E225,E222,E221,E241,E203 in my search, and at
least E501 on any autopep8 run.

Other style fixes not related to PEP8:
* Only use new-style classes. I don't think the usage of old-style
  classes was voluntary. Old-style classes are removed in Python 3.
* Convert an if/else to a one-liner in mediawiki, change docstring style
  change to a comment something that wasn't really appropriate for a
  docstring.
* Unneeded first if condition in meteofrance

Use stderr and return codes >0 when it makes sense.
Loose return code conventions:
* 1 for generic errors
* 2 for user input errors
* 3 for remote errors (not found, etc.)
* 4 for not implemented
