Fix #396

{findings | count: 'Critical'} will use environmental score by default (which is equal to base score if not set).

User can also use the following counts:

{findings | count: 'Critical':'base'}
{findings | count: 'High':'temporal'}
{findings | count: 'Medium':'environmental'}

Is there a way to get the total number from findings?

[Zeecka]

You may try {findings.length}
