CKEditor macro dialog filtering should also include technical name

Currently, the CKEditor macro selection modal allows to filter by text.

The filtering is case insensitive and returns all macros where either the translated name or the description are containing the searched text.

This can be an issue for some macros where the technical name is different from the translated name.

For instance, the documents macro is translated (in english) into Pages.

Hence, search for "documents" does not return the expected macro, which can be confusing.

I propose to also filter on the macro id when filtering.

Optionally, the macro id could be displayed aside the translate name.
