Changing a layer's name is not treated as a file modification

[Jonathan Bohren]

In Inkscape 0.47 and 0.48.1 (r9760), if the user only changes a layer name, the program does not register the modification as a change to the file and therefore will not allow the user to save the changes. In order to save a layer name modification, the user must also change some other content of the document.

Reproduced with Inkscape 0.48.1 and 0.48+devel r10419 on Mac OS X 10.5.8 (i386)
Only occurs when editing the layer name in the list view.
Not reproduced when using the menu command ('Layers > Rename layer…') or the context menu command in the list view.

Same issue already discussed in
Bug #377294 “rename layer which has no inkscape:label attribute fails” (comment #1 et seq.)

This patch adds the "rename layer" operation of the Layer list to the undo history. This causes the document to be marked as having unsaved changes and also enables the undo/redo of the layer rename.

This is the same code that is used in the Layer dialog for renaming (see layer-properties.cpp LayerPropertiesDialog::Rename::perform).
