METADATA.jl/kNN needs a version bump

[catawbasam]

The version of kNN pointed to by 0.0.0 in METADATA.jl/kNN is still using Stats rather than using StatsBase, which causes using kNN to fail with:

ERROR: Stats not found
 in require at loading.jl:47
 in include at ./boot.jl:245
 in include_from_node1 at ./loading.jl:128
 in reload_path at loading.jl:152
 in _require at loading.jl:67
 in require at loading.jl:51
while loading /home/keithc/.julia/v0.3/kNN/src/kNN.jl, in expression starting on line 6

Bumping METADATA.jl to the latest kNN update should resolve the 'Test Status: Package doesn't load' reported by http://pkg.julialang.org/.
