Define time-based response body processing

[jarrodek]

When a complex body arrives but it does not trigger the size limits the application can hand for a little while before its usable again. There should be a timeout for the response processing that kills the work after the set timeout and renders the "raw" view only.

To reproduce:
Send a binary file to HTTP bin and wait for the response. For huge files, this will hang the renderer window.

Additional steps:

• introduce the application setting for the timeout in the request section.
