issue2551179 Load config_ini.ini ... recognize minimal template demo.py Mostly taken from patch by John Kristensen (jerrykan). Tests for python3 and 2 created for minimal and jinja2 templates. Removed FIXME for special case config settings for jinja and responsive templates. config_ini.ini mechanism makes it obsolete. Demo removes config_ini.ini file in home directory. Also remove encoding of utf-8 from initial_data.py to remove SyntaxError: encoding declaration in Unicode string under python2.
