Search by catalog number: support searching in a user's collection

[php-coder]

User should be able to search by catalog number in his collection.

I suggest to add a checkbox for that. (Should we show it when collection is empty?)

Subtasks:

• Search by catalog number in user's collection: add a prototype #1087 add a prototype
• Search by catalog number in user's collection: add the simplest implementation #1098 add the simplest implementation
