Analytics doesn't support multi-site

[timbuckingham]

Only one Google Analytics profile can be associated with BigTree at the moment. This causes all the pages of a sub-site to not properly track analytics and analytics data for the sub-sites also isn't reported in the main report.

Proposed solution:

• When configuring Analytics in a multi-site environment you'll see a list of your domains and can assign a profile to each one
• When caching page views look up analytics data based on the proper domain for each page
• When viewing more detailed analytics information (and the dashboard heads up) add a switcher to switch between domains
