CutLog v6.20

We have again improved our CutLog software in more ways.

1. FlexiCut2 - new dimensioning "From edge (no kerf on side boards"
   
2. Export to XLSX fix in all optimization functions
3. core components upgraded
   
4. product-window - better handle duplicity of size
   
5. checking for new version on start
   
6. Very important internal optimizations leads to optimizations in future versions
   
7. other internal optimizations and fixes
   

All these changes tends to bring you better user experience. More ​satisfaction and less time spend on preparing production.

 Base on customer request we have added new type of dimensioning into FlexiCut2. It is basically the same as "From edge" type​. Only difference is, that from distance of first board is substracted kerf (either from first, or from second pass). It is more clear from further image
