Nicolas Dermine 07e97c38cd add getVariableCount method to TemplateProcessor
returns how many times each placeholder is present in the document

almost the same code as `getVariables`

useful when cloning a block a number of times and want to replace
placeholders that are present more than once in the block
(using the `$limit` parameter of `setValue`)
