Julia compat - requires Julia master?

[DilumAluthge]

The current Julia compat entry in Project.toml is:

julia = "1.3"

But https://github.com/StefanKarpinski/PkgServer.jl/blob/master/bin/gen_static.jl#L132 has:

    for reg_dir in readdir(depot_regs, join=true)

In Julia 1.3, readdir does not accept keyword arguments, but it does on Julia master.

So I think you need Julia master or a relatively recent Julia nightly.

As mentioned in #5 we should probably delete bin/gen_static.jl entirely and have a separate package for static serving.
