Ready for sulfur

• improved error checks
• removed parallelism (conflicts of concurrent runs)
• prepared interface for sulfuric compounds

Add option for external (local) ChemDB

• Scan for non-empty "ChemDBLocal" repertory
• If exists, propose content as available database

Compressed data files

This version implements the compression of datafiles to gain space both in MC-ChemDB and Projects storage:

• in ChemDB, Photoprocs files are gzipped (outside of ReactorUI)
• samples of chemical reaction parameters are compressed when samples are generated in ReactorUI
• outputs of reactor are gzipped
