Julia fails to build because of absence of julia-release-webserver in recent versions of julia

[Lenskiy]

Running the formula with the debug key I get
install_name_tool: can't open file: /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver (No such file or directory)
/usr/local/Library/Homebrew/formula.rb:606:in `system'
BuildError: Failed executing: install_name_tool -add_rpath /usr/local/opt/arpack-julia/lib /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver

BuildError: Failed executing: install_name_tool -add_rpath /usr/local/opt/suite-sparse-julia/lib /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver

BuildError: Failed executing: install_name_tool -add_rpath /usr/local/opt/openblas-julia/lib /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver

BuildError: Failed executing: install_name_tool -add_rpath /usr/local/lib /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver

BuildError: Failed executing: install_name_tool -add_rpath /usr/X11/lib /usr/local/Cellar/julia/HEAD/bin/julia-release-webserver

The problem is easy to fix by commenting out line 189

system "install_name_tool", "-add_rpath", rpath, "#{bin}/julia-#{target}-webserver"

There is no julia-release-webserver in recent versions of julia.

Great, this is an easy fix. I'll remove this line for now, but in the future feel free to submit pull requests and I'll gladly merge them!
