added fetchLineNumber(editor) and getLineNumber()

Browse Source 
added helper function fetchLineNumber(editor) to return the line number that the cursor is on and refactored the code to make use of this helper function in various places. Also added function getLineNumber() which will output the current line number the cursor is on.
