Fix deprecations in show.jl

[Ayushk4]

Minor deprecations and bugs (similar to #153) fixed.

The function summary in show.jl (source) is named similar to Base.summary.

@aviks What should I rename this to? Or should I extend Base.summary to support AbstractDocument, Corpus types?

This is good. Thanks @Ayushk4

One comment is that the show_repl should be moved to show(::IO, ::MIME"text/plain", c). See here for the current state of these functions: https://docs.julialang.org/en/v1/manual/types/#man-custom-pretty-printing-1

Thanks Ayush

A good ( bad ? ) news - now that this is fixed. The outputs of print and show will be changed to the ones defined in show.jl.

For eg:

• Earlier one

  julia> doc = StringDocument("this is a doc")
  StringDocument{String}("this is a doc", TextAnalysis.DocumentMetadata(Languages.English(), "Untitled Document", "Unknown Author", "Unknown Time"))

• Newer one

  julia> doc = StringDocument("This is a String Document")
  A StringDocument{String}
  * Language: Languages.English()
  * Title: Untitled Document
  * Author: Unknown Author
  * Timestamp: Unknown Time
  * Snippet: This is a String Document

  This means the documentation work done in #134, #147, #150 needs to be revised for the new changes.
