Missing dependency on Docile

[jaak-s]

It seems that IterativeSolvers depends on Docile but does not declare it (at least Pkg.clone("...iterativeSolvers.jl.git") does not install it) and later loading it gives following error in julia v0.3.5.

Docile is only required for julia 0.3.x (it is integrated into 0.4-dev), and unfortunately there is currently no way to specify this dependency conditionally in Julia's package manager.
