Subject: [PATCH] Changed monaco-adapter to respect line endings when
 calculating positions (#303)

When monaco was not using '\n' as its line ending then the calculations for text positions were all incorrect which caused the creation of faulty TextOps

This simply uses the monaco.getModel().getEOF() to access the currently used line feed and calculate positions based on that.
