Do not append profiling block when "Content-Type: application/json" response header is set

[heldchen]

some extension (Magme WebForms Pro 2) use an iframe to post form data and get json back. unfortunately, Mirasvit_Profiler then appends its profiling block to the result, breaking the javascript execution.

could the extension check if a response header with content-type "application/json" is set and then not output the block?

turns out its pretty simple to achieve, please see the following patch:

 }
