Flag stray lakes

[geohacker]

@bkowshik @amishas157 @manoharuss - can we write a compare function to flag stray water features? Any new water features by a new user.

@geohacker also/instead: water bodies that drown buildings, roads, etc. -- and prioritize based on population in the affected area?

[bkowshik]

For the first iteration of the compare function, I am going with the following:

A feature is a water feature if it has:

• natural=water
• water=*

A user is a new user if he/she has less than 10 changesets.
