Improve activity admin status messages

[fanquake]

When marking and item as "Not Spam" from the drop down, you get the error "An error occured when updating Activity ID #XXX."

Small side note here, occurred is spelt wrong..

Thanks, fixed the typo in a commit about to go into #3660. Also on this new version, I can't recreate this bug. Can you svn up and try to recreate it?

(In [5484]) Activity admin iteration. See #3660.

• Add remaining activity properties to the edit screen.
• Add new contextual help to the edit screen.
• Add support for 2 columns to the edit screen.
• Fix a typo (props fanquake, see #3822).
• Update BP_Activity_Activity::save() method to fix a bug where an update operation with no changes was reported as an error.
• Update activity admin CSS, bump version number.

I can no longer reproduce, so it must have been fixed.

Was going to create a new ticket, but this is related. When you mark an item as not spam, you see the message "1 activity restored from the spam." Should this be changed to "1 activity item restored from the spam." ?

"%d activity items successfully unspammed"

or

"%d activity items successfully rescued from the spam abyss" works too

I don't like abysses. With that said, are we going for "activities" or "activity items" for >1? Need to change all of the status messages at the top of bp_activity_admin_index() for consistency if this one changes.

[johnjamesjacoby]

"Activity items" please.
