uDig web map tiles enhancements

Many of you for sure know that uDig has the ability to show Web Map Tiles.

push the next button and find a long list of available web map tile servers (which we should probably check).


There is also the possibility to select a custom server. This is very handy, but had 2 problems:

This will be extrememly helpful for those like us that use uDig with BeeGIS field extensions out in the field on netbooks. The base dataset gets extremely lightweight to load and rasters can be prepared to be fast and easy.
