README.rst: Add Slackware http://slackbuilds.org/repository/14.1/system/glances/

Python 3.4 is now supported.
Add Python 3.4 to .travis.yml.

While I was there:
- complete overhaul of the CVS class
- fix open file issue w/ python3
- has_key() option was removed in python3
- usage simplified: there is no need to define the CVS filename, only the
  output folder, as for the HTML export
- update help, doc and man accordingly
- fix typos

few mispelling errors

German updated to 1.7.6

New i18n gen

stupid mistake, where I forgot to replace XX with $1
added locale information to generated po-file
removed redundant positive output

to help a future maintainer understand the crap I wrote there

no need to manually generate po/pot files anymore
generation of pot files and updating po files now before translating

Add new z key in man page

Fix case.

Implement toggle of process list display

Adapt to psutil 2.0.0 API.

Fixed psutil 0.5.x support on Windows

Don't know why adding "None" as second default helps.

API changed.
https://psutil.googlecode.com/hg/HISTORY

Tested with 0.5.1, 1.2.1, 2.0.0

Parsing and displaying the process list takes a sometimes significant
amount of resources.  Since there is already a mechanism in place to run
glances with the process list disabled, it was easy to add a toggle to
the __catchKey function.

Fix lintian warning from debian packaging

Distinguish between mandatory and optional dependencies.
