1.0.1 fixes

Great work on the IDE, I've been using it for a few months now.

However with the latest version (tagged 1.0.1), I have found that the newLineMode setting has stopped working (looks like it was removed at some point, hopefully not intentionally)

This pull request adds support for newLineMode back into the editor.

I also found that the build process did not work on Linux because it has case sensitive paths, and the casing for several files in the Jakefile did not match the actual casing of the files, so I have renamed them accordingly.
