Adds Cylinder helper class for cylinder info access in grantlee templates

to allow grantlee to access individual fields of the cylinder_t struct
rather than a string representation of the whole cylinder info using a
grantlee structure like this one:
	<table class="table_class">
		<tr>
			<td>Cylinder</td>
			<td>Start press.</td>
			<td>End press.</td>
			<td>Gas mix</td>
		</tr>
		{% for cylinderObject in dive.cylinderObjects %}
		<tr>
			<td>{{ cylinderObject.description }}</td>
			<td>{{ cylinderObject.startPressure }}</td>
			<td>{{ cylinderObject.endPressure }}</td>
			<td>{{ cylinderObject.gasMix }}</td>
		</tr>
		{% endfor %}
	</table>
