Bug 144375

This is an enhancement suggestion that can benefit accessibility in Writer documents and user experience.

In the Tools - LibreOffice Writer - Autocaption dialog for images, Frames and other OLE objects:

1) Add a checkbox to copy caption category and number to Illustration "Name" property, overwriting existing random name.
2) Add a checkbox to copy caption text to "Description", overwriting the existing description.
3) Add a checkbox to copy caption category, number and description to the "Alternative" property;

Rationale
---------
Images, frames and OLE objects names are generated internally to ensure name uniqueness on creation and on import of contents. However, the name displayed in the navigator is too often meaningless and unordered, thus making the navigator a limited tool if the object name is not properly named.

By adding the caption info in the name, alt and description, it turns the navigator a better tool. 

It also improve accessibility of the document by filling these properties with the right contents.

Alternatives
------------
Since the objects has getByName() it is advisable to have these overwrites as option in the AutoCaption.

An alternative is a command attached in the context menu of the image in the Navigator to execute the overwrites. That requires manual user intervention, but is a lot safer.
