Rename XLinks Upon Object or Document Rename

[gbroques]

There are references to document and object names in XLinks that should be renamed when renaming a reference.

Need to be careful to not to rename an XLink if another reference to that file or object still exists.

In this case we would add an XLink and increment the count and docs attribute.

<XLinks count="1" docs="1">
    <DocMap name="Master" label="Master" index="0"/>
    <XLink file="Master.FCStd" stamp="2021-07-25T18:40:15Z" name="Spreadsheet"/>
</XLinks>

<XLinks count="2" docs="2">
    <DocMap name="Master" label="Master" index="1"/>
    <DocMap name="Cube" label="Cube" index="0"/>
    <XLink file="Cube.FCStd" stamp="2021-07-25T20:03:03Z" name="Box"/>
    <XLink file="Master.FCStd" stamp="2021-07-25T18:40:15Z" name="Spreadsheet"/>
</XLinks>
