CeSymm bug fixes

* Ignore trailing whitespace in user input
* Output order 1 for insignificant alignments
Packaging changes
* runCESymm.sh looks for the jar in its own directory
  rather than in the current directory (good for scripting)
* Package as 'symmetry-tools-1.0.0' rather than
  'RCSB Symmetry Tools_2014-01-01'
