Implement the .include statement

This needed some heavy lifting when it comes to how files were located.
This means that statements like .include/.incbin now take into
consideration a new list made out of SourceInfo, which holds enough
information to translate from which file a node comes from. This has
also been added into errors, so they are more informative on what went
wrong.

In order to tests this, besides all the regular unit tests, a new e2e
test has been added.
