Restore help tooltips

[etj]

When editing a dataset, there's a space between every upper input and the lower label

that is a badly rendered <span> info tooltip:

By replacing the proper fa fa-info-circle in place of the old icon-info-sign I get this:

• The info icon should be placed close to the relevant input label
• When hovering, the tooltip should be displayed

Macro help_block -->

ckanext-dcatapit/ckanext/dcatapit/templates/macros/dcatapit_form_macros.html

Lines 473 to 479 in 1292090

	{% macro help_block(content) %}
	{% if content %}
	<span class="inline-block" data-module="dcatapit-help">
	<i class="icon-info-sign size-12" title="{{ content }}"></i>
	</span>
	{% endif %}
	{% endmacro %}

The macro is only called within the same file.

Related js should be at

ckanext-dcatapit/ckanext/dcatapit/fanstatic/dcatapit.js

Lines 577 to 587 in 1292090

	ckan.module('dcatapit-help', function($){
	var help = {
	initialize: function(){
	$.proxyAll(this, /_on/);
	$(this.el.find('i')).tooltip();
	}
	}
	return $.extend({}, help);
	});

I guess that most of the macro code has been taken from an older version of CKAN.
