Merge branch 'release/2.1.1' into develop
Fixed issue where site title/logo would link to the base site in multisite installs
Fixes #84

The 'agrilife_featured_post' saving feature was comparing instead of assigning value to the $featured variable.
Now temporarily saving the map image as a base64 encoded transient to cut down on API calls.
Transient is reset after theme options are updated.

Fixes #88
Updated readme.
Merge branch 'release/2.2'
