[josm-dev] new confirmation dialog for presets

[Malcolm Herring]

There is a conflict here. There are circumstances where a confirmation 
dialog is wanted by the preset author - this is when there are <label> 
and/or <link> that are required to be displayed.

Maybe a solution is to auto-detect this situation - if there are only 
<key> elements, then the tags are set without confirmation, but if there 
are also <label> or <link> elements, then a confirmation is required. 
Maybe also in the <item> header, a confirm="yes/no/auto" parameter might 
be useful.
