rename
Relation#uniq
to Relation#distinct
. #uniq
still works.
The similarity of `Relation#uniq` to `Array#uniq` is confusing. Since our Relation API is close to SQL terms I renamed `#uniq` to `#distinct`. There is no deprecation. `#uniq` and `#uniq!` are aliases and will continue to work. I also updated the documentation to promote the use of `#distinct`.

@senny Removing
:uniq
in favor of:distinct
causes a build problem for activerecord-deprecated_finders (see rails/activerecord-deprecated_finders#8).Do you know if that should be fixed in AR-deprecated_finders or in Rails itself?
