Project items are now represented directly in nodes opening up more versatility and possibilities. This is the first iteration of this and will be buggy. Need to test thoroughly.

* Since Qt's default function doesn't exit at the end of the document, it ends up consistently
|
|
* throwing a "premature end of document" error. We have our own function here that does essentially
|
|
* the same thing but fixes that issue.
