WFS shapefile output generates different names at each call when a field exceeds 10 chars

Mauro, the plan of attack for this one is to turn the map into a variable and have it reset for each generated shapefile. Think of the multi shapefile output case, what fields are stored in one shapefile is of no concern for the next one.

Also, we should keep the first truncated name as is (truncated, no postfix attached) and start adding numbers only when the subsequent duplicates (if any) are found.

The included patch should solve the issue (please, give it a review). In short:

• the map is no more a field, but it's created in the createAttributeMappings method for each different schema
• for the postfix not to be attached to the first truncated field, it should already be done that way (maybe the previous issue was hiding it, due to the counters not resetting)

Ah, thank you. I'll merge it in the larger work I'm doing (solving another issue at the same time, GEOS-3381)

Hopefully fixed on 1.7.x and trunk.
I gave the nightly build a kick so you can grab today's binary and it should contain the fix already, let me know if this works for you. Between this issue and the other one I had to rework the code more than I would have liked to.
