Evine will occasionally crash while fetching a lot of results

The fatal error is fatal error: concurrent map writes (generally crashes before reaching 1k results) This does not happen when running evine with only a single thread

output.log

The error occurs in line 1417 of evine.go

// getSource run with each URL and extract links from the URL page
func getSource(uri string) ([]string, error) {
        if !urlExcluding(uri) {
                return []string{}, nil
        }
        time.Sleep(time.Duration(OPTIONS.Delay) * time.Millisecond)
        text, statusCode, err := request(uri)
        if err != nil {
                return []string{}, err
        }
        if !statusCodeExcluding(statusCode) {
                return []string{}, nil
        }
        putting(VIEWS_OBJ["RESPONSE"], " > " + uri)
        RESULTS.Pages += text
        RESULTS.PageByURL[uri] = text // < -- THE ERROR IS HERE
        allURLs := getURLs(text)
        allURLs = urlCategory(allURLs)
        refStatusLine(fmt.Sprintf("[Elapsed:%fs] | [Obtained:%d] | [%s]", sinceTime(), len(RESULTS.URLs), uri))
        return allURLs, nil
}

you have to add a Mutex.Lock(). Im going to make a pull request.

Made pull request that I have verified to fix the issue
