Added a linter for script parsing errors. Requires linter package installed and after pulling changes cd into repo and execute apm install to get atom-linter node module. Also requires a path to a standalone engine which defaults to 'livecode' assuming you have a symlink to a standalone engine somewhere in the current $PATH. Otherwise you can set the path under the language-livecode settings. TODO: GenerateSnippets stack should probably update scriptErrors.txt (hopefully from the livened repo somewhere) too to ensure it's updated.
