Require and placeholder

[KittyGiraudel]

We have a bug with placeholders when implicitly required.

When writing:

/**
 * @requires %placeholder
 */

We end up with (in the console):

Item <item> requires %placeholder from type function but this item doesn't exist.

Because of %, {placeholder} should be optional, exactly like $ and variables. Yet, it doesn't work.

A fix like this should probably be added.

Excellent @pascalduez. Please make sure both master and develop get the fix, then bump the patch on master.
