[patch] TMSLayer: put option in tile context menu to hide errors

[cmuelle8]

hi,

on ​http://cycling.lonvia.de/ a new cycling map is available. it is different from OCM to the point that it uses just overlay tiles (routes are rendered, the rest is transparent, so any base layer can be used). overlay tiles are only generated if a route is contained on the tile, so to use this properly as a TMS background in josm, an option to hide errors is necessary. i patched TMSLayer.java to have a checkbox option "Show Errors", which by default is on (previous default behavior). it's a small patch and should not cause you regression trouble ;)

patch in Show Errors option to hide error messages on tiles in the view pane

Eclipse' formatter killed the curly braces and produced dangling else's. Does anyone have a quick hint where to turn it off? thx
