#55: Uses IOUtils.toString method with explicit charset. Closes stream with try-with-resource block.

[sebast26]

Closes #55

Based on JavaDoc for IOUtils.toString (https://commons.apache.org/proper/commons-io/javadocs/api-2.6/org/apache/commons/io/IOUtils.html#toString-java.net.URL-)

Also I close streams because IOUtils by default do not close it (please follow class JavaDoc: "Wherever possible, the methods in this class do not flush or close the stream").
