Julia: Print Symbol("true") as Symbol("true") instead of :true

[Seelengrab]

This came up on slack when we were trying to create a Symbol("true") via :true.

julia> :true === true
true

julia> :true == Symbol("true")
false

julia> Symbol("true")
:true

@Keno proposed to change to printing to Symbol("true"), to make it clear that the symbol can't be created by using :. Further, Symbol(true) and the symbols of false should probably be handled the same, since the docstring for Symbol states that the string representation of the arguments is used to create the symbol.

help?> Symbol
search: Symbol

  Symbol(x...) -> Symbol

  Create a Symbol by concatenating the string representations of the arguments together.

Sounds good to me and would help explain:

julia> Symbol(true) == Symbol("true")
true

Especially since

julia> Symbol(1)
Symbol("1")

it would make since for

julia> Symbol(true)
Symbol("true")

Bug fix or minor change? I would probably lean towards minor change to be safe.

[Selich]

I will look into it if you don't mind.
