]link.break -a has no force option

**Describe the bug**
]link.break will not work if any files or objects are out of sync. Instead it insists that a ]link.resync operation must be performed.

While that's often a useful warning, ]link.break ought to allow -force to break all the current set of links regardless of whether things are out of sync.

**To Reproduce**
1. Create a namespace
2. Link that namespace to a directory
3. Take a series of action that will put the namespace out of sync with the directory.
That can include adding removing files from the directory, or use )erase in the workspace.
4. ]link.break -force namespace
5. Error message: Unrecognized option.

**Expected behaviour**

]link.break -force namespace

Should break all the links between the workspace regardless of whether the two are out of sync.
Warnings about things being out of sync are appropriate, but not allowing the break operation is unacceptable.
