fixed a major discrepancy - now matches perl output for gregorian to saka (saka to kolla problems remain);
stricter linting with modified JSHint options;
introduced globals.JulianDay in place of globals.year, globals.month and globals.day;
new tests for getMalayalaMasaName, getMalayalaNaksatraName;
require statement in tests don't need the .js extension either;
