Quality life update

Major changes

• DialogBox constructor now accept an argument global_win. It allows defining a curses window where to write by default. As a result, the win parameter of char_by_char and word_by_word methods has become optional and is now accepted as a second argument.
  This feature is useful when dealing with many DialogBox methods calls.

API changes

• PanicError now inherits of KeyboardInterrupt exception.

• An error ValueNotInBound (which inherits of ValueError) is now raised if inconsistent values are passed to DialogBox during instantiation (see related documentation).

• Current window is now passed to second argument of callbacks during char_by_char and word_by_word execution.

• Arguments are now passed to callbacks:

  • For char_by_char method:
    • the instance of the class used (self), current curses window, character written and index of the character in the current word being written.
  • For word_by_word method:
    • the instance of the class used (self), current curses window and word written.

• char_by_char and word_by_word now returns text argument that are passed to them at the end of their scrolling.

• Improve documentation.

Bug fix

• Fix a bug introduced in previous version: default value of downtime_chars_delay
  parameter from DialogBox was set on 60 (insteed 600)
• Since their introduction, DialogBox.positions and DialogBox.dimension returns erroneous values. This is fixed.
