19823	Advanced Preferences could not export selected items if they have default values	mdk	team	"==== What steps will reproduce the problem?
1. Select some values in Advanced Preferences
2. Export Selected Items
3. Open Export file in an editor

==== What is the expected result?
All selected preference items results in a line in the export file.

==== What happens instead?
Only items with non default values are exported (yellow backgrond in Preferences).
Items with default values (white background) are ignored.

==== Please provide any additional information below. Attach a screenshot if possible.
How can I export a default preference value? What if I want to have two files for HiDPI Scaling 2.0 and 1.0 for quickly change between both settings? It's not possible to export the 1.0 scaling, because these items are missing in such a fille. I have different JOSM installations. How can I export the reset of a preference item on one installation and import (the reset) in an other one? 

I see two possible solutions:
1. Don't ignore and export the default value.
2. Export the item not with value= but with something like reset=true.
