t/data/dmel_2Lchunk.gb: Updated features locations to use current
definitions (http://www.insdc.org/documents/feature_table.html#3.4.3).
This is necessary for unflattener tests to keep passing after
the next commit.
Bio/Location/Split.pm: Final fix for issue #76. From now on,
min_start/end and max_start/end subroutines will not order
sublocations by default, which was breaking cut by origin features
(had to add a little code from sub_Location to handle special cases
too). Also, fixed "end_pos_type" to return the last sublocation
value, because it was not working for partial reverse frameshifted
genes (like "complement(join(94468..94578,94578..>94889))"). Updated
several tests to reflect these changes.
