Enhance JOSM bug report system

[Don-vip]

We have more and more bug reports without all the required information we need to reproduce it quickly or have a better understanding of it.

Users are often available to reply to our requests, but sometimes they are not. I'm sure there are some of "needinfo anonymous" tickets that could have been easily fixed if we had the required info.

Even when reporters willingly help us, it's often a loss of time, both for them and us.

I think of several enhancements that could help us to improve the situation when the user chooses to report a bug:

• Increase the size limit of text that can be pasted to our Trac instance, in order to avoid incomplete stracktraces
• Add some wiki formatting to have nicer bug reports
• Automatically attach the commands stack that led to the JOSM bug
• Automatically attach some of the JOSM preferences, to be discussed to avoid privacy concerns
• Automatically export and attach active layers when the crash occurred (to be also discussed for privacy concerns). An external and configurable free file hosting service support may be implemented to upload large .osm files that could not be stored on this Trac instance.
