Fixed HardClipping and Interval containment 

* Hard clipping was wrongfully hard clipping unmapped reads while soft clipping then hard clipping mapped reads. Now we throw exception if we try to hard/soft clip unmapped reads and use the soft->hard clip procedure fore every mapped read.

 * Interval containment needed a <= and >= to make sure it caught the borders right.
