Add update_title config option

[etpinard]

fixes #101

• add update_title String field to DashConfig struct
• use `"Updating..." as default
• inject its value into the frontend, to make it available to the dash renderer

TODO:

• should we allow update_title=nothing inputs?
• add tests

except for the None part.

Only supporting '' is fine by me.

re: tests - dynamic behavior is covered by the tests in plotly/dash#1315, here it would be fine to just assert dashjl.driver.execute_script("return store.getState().config.update_title") == expected for the default and one non-default case.

Thanks for tips!

LGTM! I've enabled forks in CircleCI, didn't realize we hadn't done that yet. Would you push an empty commit to see if the tests will run?

@waralex This step fails for forks:

Dash.jl/test/ci_prepare.jl

Line 7 in cb64b94

Pkg.add(PackageSpec(url="https://github.com/plotly/Dash.jl.git", rev=ENV["CIRCLE_BRANCH"]))

But we already have the appropriate version of the code in a local directory, can't we just use that?

Yes, we can use Pkg.develop instead of Pkg.add

 Pkg.develop(pkg::Union{String, Vector{String}}; io::IO=DEFAULT_IO[])
  Pkg.develop(pkgs::Union{Packagespec, Vector{Packagespec}}; io::IO=DEFAULT_IO[])

  Make a package available for development by tracking it by path. If pkg is given with only a name or by a URL, the package will be downloaded to the location specified by the environment variable JULIA_PKG_DEVDIR, with .julia/dev as the default.

  If pkg is given as a local path, the package at that path will be tracked.

  Examples
  ≡≡≡≡≡≡≡≡≡≡

  # By name
  Pkg.develop("Example")

  # By url
  Pkg.develop(url="https://github.com/JuliaLang/Compat.jl")

  # By path
  Pkg.develop(path="MyJuliaPackages/Package.jl")

  See also PackageSpec

@alexcjohnson, @etpinard In fact, there is another problem - the components are placed by direct reference to git, and not through the package repository. Apparently I wrote this file when the components were not registered yet. I fixed it in this PR #104. In that #104 unit tests pass, let's check in current one. Perhaps you should just copy the changes from #104 to this PR and merge them within current PR

Great - Thanks @etpinard ! 💃
