Make option for upload=true/false by default available in expert mode

[skyper]

What steps will reproduce the problem?

1. start josm with no preferences
2. load a file​
3. change to expert mode
4. try to change upload=true/false in context menu of layer toggle dialog.

What is the expected result?

An entry to toggle upload=*

What happens instead?

No entry

Please provide any additional information below. Attach a screenshot if possible.

Still have to enable this hidden option in advance preferences, though it is really useful.

The entry could be a check box to always display the current value. The current value is only available under info atm.
