Asset missing a hook

Here is updated patch which adds new hook and fixes two other issues (with saving asset on "override asset" form).

I think it should be separated patches.
+ please describe your new hook in the asset.api.php file.

Here is a new version with hook described in asset.api.php file.

And yes, I agree separate patches should be done for other issues - will indeed create them recently.

Ok for me.
Thanks.

Hi guys,

it's great idea to complete this functionality,
but current hook in patch is not enough.
Because we also need to add a way to hook into handling of each type, see assets_get_placeholder().
Because of this, real overridden values will not be stored within tag.

Guys, thanks for work.
Accordingly to the last version of Asset module logic of this function was improved and the hook was added.
Pushed to dev version.
