The rope uses a large leaf-node text length, so in the vast majority of
cases this ends up being the same as directly storing the string data.
But in the case that the line becomes extremely long, this will allow
for reasonable performance
File loading is now the responsibility of the Buffer, which allows
it to do some weird internal stuff to make it faster.
Also, using custom code for scanning the text, so all line endings
are handled now, not just LF and CRLF.
A LineFormatter determines how a line of text is visually displayed in
2d space. This allows both the Console and GUI version of the editor
to share the same buffer code whilst still handling the differing ways
in which both handle visual display.
Most of the UI and editor code is either commented out or not included
in the compile right now. This is temporary while I get the basic
text code working again.
