Preserve image aspect ratio in results

Noticed that images are often distorted in the results due to a hard minimum height.  This keeps the 4-per-row image results consistent in row height without distorting wider images.

[fix] Read utf-8 files (settings, languages, currency) with Python3.5

Related to discussion in #1124
The io.open import is necessary for python2

Python3.5 is still the default Python3 version in
Debian Stretch (stable) and Ubuntu 16.04 LTS
https://packages.debian.org/source/stretch/python3-defaults
https://packages.ubuntu.com/source/xenial/python/python3-defaults

Make Python 3 able to read settings files with Unicode characters

Fix yacy engine

Closes #1064

SearX currently doesn't start up when run with Python 3 as it tries to parse the
settings.yml file with ASCII codecs.
There are similar problems with engines_languages.json and currencies.json
Python 3 requires that files with Unicode characters be read with a 'b' flag.
This also works with Python 2 and hence can be integrated into the main source
code.

Tested with the latest Python 3.6.4rc1 on Debian unstable.
