Deprecation patrol.

the same issues as JavaConversions with respect to overloading implicit
methods making them inaccessible to view bounds. Fixed JavaConverters.
Added a warning for when people overload parameterized implicits: in
almost all cases the name is irrelevant so there's little point in
unwittingly suffering degraded functionality. No review.
