JOSM should display a setup assistant / "getting started" wizard on first run

[Don-vip]

Everytime I run JOSM for the first time on a new machine, I have to setup a lot of things to match my personal preferences, some of them are necessary to work (OSM account, network preferences), some of them are optional but quite frequent I think (disable dynamic buttons on large screens, setup language, projection, install some plugins).

Many of these choices will require a restart, and only experienced users know which settings can be customized together at once in order to minimize the number of restarts.

Users should go through a setup assistant to help them to configure these essential things the first time they run JOSM.

I am not sure if this is worse the effort.

It is already possible to export your preferences and to set them on start up with command line options.

Some warnings are false positives, see #7482.

Most changes should work without restart (like changing the network settings) and if a restart is needed, a single one should be sufficient. This should be mentioned in the warning message.

One thing such a setup wizard should ask is "do you want to activate JOSM remote control" ?

So many sites are using it, but new JOSM users usually get stuck because of the remote control being off...

We need at least remote control, account settings (optionally) and proxy settings (if no internet connection is detected).

Maybe import of preferences and the updatable list of most popular plugins would also help.

I plan also to work on the ability of switching on and off (without restart) as many parameters as I can :) I started with r5661 and r5689
