- Updated Evidences to also have the NonNumericSequence
- Updated Clusterer to cluster based on the NonNumericSequence from evidences
    - Doing this preserves Evidences (especially from MzIdent format files) which have the same sequence, but with modifications
- Added a flag to LcmsDataSet for if the dataset had been analyzed previously to address duplicate analysis
- Updated ConsensusTarget
    - CleanSequence is the sequence stored in the database
    - All sequences are rebuild upon addition of an evidence
