OrderedDict and OrderedSet constructor does not work properly on variable tuple tupes

[yuyichao]

Best shown with the example below.

julia> Set{(Symbol...)}([(:a,)])
Set((Symbol...,)[(:a,)])

julia> OrderedSet{(Symbol...)}([(:a,)])
ERROR: `convert` has no method matching convert(::Type{(Symbol...,)}, ::Array{(Symbol,),1})
Closest candidates are:
  convert(::Type{T}, ::T)
  convert(::(Type{T<:Top},Type{T<:Top}...), ::(Any,Any...))
  convert(::Type{Ptr{Void}}, ::Array{T,N})

Thanks for the report. What version of Julia are you running?

I won't be able to get to this until next week, so if you figure out a fix or anyone else has a chance up look at this, a PR would be much appreciated.

Fixed in the latest release. Sorry this took so long!
