adsense 5.x-2.0

Changes since 5.x-1.6:

Features:

• Has a new hook_adsense that can be used by other modules to determine which Google Adsense ID to show. This opens new doors for revenue sharing. Watch for the blog post. This makes revenue sharing completely pluggable via this API. Modules can choose to do the sharing by role, by taxonomy, by userpoints, or other custom criteria or by anything else imaginable.
• No longer depends on the profile module for sites that don't need revenue sharing.
• Uninstall for all the included modules.
• Help is now easier to maintain in separate files with plain HTML in here docs.

Bug fixes:

• #220534 Fix for revenue sharing not working: site owner Adsense ID always returned.
• #221001 documentation patch by bcobin, expanded by kbahey. Added hint on using moduleweight module when adsense section targeting is messing up the display of other components of the page.
• #224561 by salgar and kbahey, cache the client ID of the site owner as well.
• Add a message in setting if cache is enabled, and revenue sharing is enabled that they conflict with each other, so the user knows what to expect.
• Better error messages when configurations are out of whack.
• Error handling is now local for each module.
