Caja does not have option to change properties of symbolic link

[Norbert]

Steps to reproduce:
1. have `file1` somewhere
2. make symbolic link to `file1` as `symlink1` (for example with Caja: Make Link or <Ctrl+M>)
3. rename `file1` to new name (now `symlink1` is broken)
4. try to edit `symlink1` properties to point to the new name

Expected results:
* Caja allows to change properties of the symbolic link

Actual results:
* Caja does not allow to change properties of the symbolic link

This is a feature request. I wonder if it could be accomplished with an extension, rather than a direct code change in caja.
