Selecting of terms, termCollections and clients

Since admin, API and PM-users should have the possibility to search all clients and collections, there is the need to be able to narrow this search in the termPortal. Above the search field there will be 

• A tag field to select the client(s) to search
• A tag field to select the termCollection(s) to search.
  • This tag field only shows termCollections belonging to the selected clients
• A drop-down to narrow the search for terms along the processStatus of the terms (unprocessed, provisionallyProcessed, finalized; these values need to be translateable)

The tag fields for clients and termCollections are only available, if the user is able to search more than one client or termCollection.
If the user searches more than one termCollection or client, behind every term the client- and termCollection-names are displayed in square brackets like this: [CUSTOMERNAME; termCollectionNAME]
