Add support for Ruby bang and question methods

* The ::find method of tag-reader.coffee uses getCurrentWordBufferRange()
  to pull in the current word to pull in the current tag. Passing in a
  custom regexp to getCurrentWordBufferRange() determines what constitutes
  a word.

* Obtain the charAfterWord by incrementing the row by one. If the character
  is a question mark or exclamation point, append charAfterWord to word
  and search the whole thing.
