Spacing
Fix some errors in the tests
Code style
Change back to `get_post()`
Meta multiselect fields didn't get saved if the meta key was not meta-robots-adv.
Only explode on comma if the mulitselect is the meta-robots-adv field, other multiselect fields (should) use serialized data.
Make the check for whether the 'edit files' admin page should be shown consistent

Check was being done differently in three different places, now changed to consistent function call.
Remove `function_exists( 'is_multisite' )` check

As min requirement for the plugin is nowadays well above WP 3.0, the check for `function_exists` on `is_multisite` is no longer needed, removed these elsewhere.
Changed the check for file editing admin screen to use WP native `current_user_can`
Fix: taxonomy meta field description was only shown for text fields
Fix issue #1158 - Show taxonomy index meta field regardless of blog-wide setting
esc_html the tax met field description on function call, not within function to allow passing some html
