Feature request: Opt-in survey capability

[jqnatividad]

It'd be nice if whenever self-update runs, for it to optionally collect some statistics with the user's opt-in, and return the survey data to the developer.

Some information that can possibly be collected by the survey:

• hardware info (platform, number of CPUs, memory available, etc.)
• IP address (so developer can geocode where his/her users are)
• what version they are on, and if they upgraded

and perhaps, the survey can be collected using the Google Forms API - with some prior setup of course...

ended up implementing this in the project itself - https://github.com/jqnatividad/qsv/pull/358
