Language Support

Refactoring LESS support into an extension

See branch dk/less-refactoring

• Idea: rename LESS to MORE and add an extension that adds support for MORE
• Added an extension that just requires the CodeMirror mode
  Result: Called EditorUtils.js _getModeFromFileExtensions with an unhandled file extension: more (EditorUtils.js:163)
• Task: Add an easy way to map a file extension to a CodeMirror mode
• Monkey-patched getModeFromFileExtensions to use file extension as mode name if such a mode exists
• Task: Load (language) extensions earlier to support their CodeMirror modes for the file automatically opened at startup (last open file)
• Added a function that changes the mode of current editors if (after adding the new mode) a different one would be used when re-opening the editor
• Task: Allow extensions to define how to add comments for a specific CodeMirror mode (in progress)
• Monkey patching not easily possible due to references to internal functions. A difficulty when making comments more generic is that we rely on the defined comment symbols to be completely contained in one CodeMirror token. I.e. we cannot define "//~" as the prefix for line comments (like SciTE does) because it is not a prefix of the "//" token.
