No completion for symbolic data

[joseferminj]

No completion for symbolic data. It could be useful that the list of autocomplete suggestions includes all the symbolic data used in the current file. For example,

(define (attach-tag type-tag contents)
  (if (equal? type-tag 'scheme-number)
    contents
    (cons type-tag contents)))

while editing another function, the sugesstion list should include 'scheme-number

Also, it would be a plus to be able to auto-complete special characters, e.g. #\newline
