Implemented new entry point to support a swing version of ldif sort.
Implemented basic version of helper class GridBagConstraintsBuilder.
Extended SwingLdifSort with some elements.
JList with ldif files now resizes correct.
Just use NORTH, EAST, SOUTH and WEST to position the elements in the GridBagLayout cells.
Added remaining components. The layout of the cancle and the sort button is not as wanted.
