Provide ability to select multiple pages and then save them to a new document

[nbelyh]

There should be an option to move the files

The user should be able to select tabs based on:

• Tabs that are selected using the standard tab selection feature
• Search based on the tab name e.g. product*
• Search based on regular expressions searching the tab name e.g. .product.

Use case:

• Documents with large numbers of pages become unwieldy
• Sometimes the pages need to be split out into dedicated files e.g. for a particular product
