Began fixing standalones

* stopped closing the file, instead use a variable
  so I can reach the end of the file and seek back

* moved literal yielding to the end of the tokenize function
  so I can remove whitespace from it if it's before a standalone

* stopped set_delimiter? from continuing the while loop
  so I can handle the standalone

* added standalone handling, which checks the left and the right
  parts of every tag to see if it's all alone on a line. And if so
  it will edit the whitespace in the literals
