Implement better handling of a request in case a client abandoned it

[ipolevoy]

There is a strange case happens when a client requests a long download and then abandons the request. For instance, the download is taking 30 seconds, but the user closes the browser tab in the middle of the request. In case like that, ActiveWeb is catching this exception, and thinking that there is "something" wrong, is trying to render an error page. However, there is no browser to render it on, and it spirals with one exception after the other. Basically, this case was never considered :(.
The exceptions below are printed from a single request as a reaction to a browser abandoning it.

The goal of this task is to:

1. Not treat this as a crisis
2. Not print any exceptions
3. Not log anything at the ERROR level
4. Print something indicating that the client abandoned the request and just moved on. (at the INFO level)
