Update support page

[agjohnson]

This addresses a few issues with the support page:

• The first section mentions Stack Overflow, but we should probably
  highlight our search first
• Adds some boundaries on our user support
  • Adds example questions back for user support
  • Directly calls out what we don't support
• Description of our support is broken up and needed a few updates
  • Mentions reponse time of 1 day, which is accurate but doesn't match
    our pricing
  • Mention our support hours
• Cleans up some of the language

Is this true? We answer sometimes in EU time, but not always. Not sure if we even put business hours here, since we have a multiple day response time?

Suggested change

	Our team responds to support requests during our normal business hours,
	Monday through Friday, 8:00am to 5:00pm Pacific time.
	We will reply within 2 business days or earlier for most plans.
	Our team responds to support requests by priority order of custom plan.
	We will reply within 2 business days on most plans,
	though we often reply quicker.
	Increased support responsiveness or SLAs are available via plan upgrades.

Perhaps something like this?

Yeah something like that probably makes more sense. I thought we had support hours defined somewhere publicly, but I'm not finding any obvious mention of it.

I tuned this up more and added the upgrade notes, that's a good addition here. I kept the focus on 2 day response time though, to keep 1 day response time as a solid upgrade.
