Finish Dam Crests layer

[Jdgilby]

This layer needs attributes:
"Structure Source" with options 'Natural', 'Artificial', and 'Unknown'
"Dam State" with options 'Breached', 'Intact', 'Blown Out'
"Crest Type" with options 'Active', 'Inactive'.
"Confidence" with options 'High', 'Medium', 'Low'.

This is a RIM layer

@Jdgilby Is this a new layer or retread of the existing Dam Crests layer (under Assessments/Beaver Dam Building)?

[Jdgilby]

@KellyMWhitehead Ya same layer as before, reworked a little. Things might change in the next version, but hopefully not.

Added to Version 0.9

@KellyMWhitehead there are a bunch of these that seem like maybe you did them, maybe you didn't? Please assign to @Jdgilby if they need testing. @Jdgilby close if you are satisfied, and reassign to @KellyMWhitehead if they need more work.

@philipbaileynar and @Jdgilby and I missed these in our roundup of 1.0 release tasks. I am assigning this to 1.0, if it is unrealistic, you can move this to 1.1.
