  1. Rewrite default template to handle nested ifs, != and env vars in if

    The awk script now performs all processing in the BEGIN block using an
    implementation that is capable of handling if statements which contain nested
    if statments (fixes yadm-dev#436). To make nested ifs look better, if, else and endif
    lines can now have optional whitespace before {%.
    
    Includes are now handled in the same way as the main file which means that
    included files can both include other files and have if statements in addition
    to variables (fixes yadm-dev#406). Include lines can now also have optional whitespace
    before {%.
    
    All variables are handled in the same way now so it's now possible to use env
    variables in if statements (fixes yadm-dev#488).
    
    Also add support for != in addition to == (fixes yadm-dev#358). Thus it's now
    e.g. possible to check if a variable is set (yadm-dev#477) by doing:
    
    {% if yadm.class != ""%}
    Class is set to {{ yadm.class }}
    {% endif %}
    
    A non-existing yadm or env variable is now replaced with the empty string.
