- switched to accessing versioned standard-reconcile app

- standardized preference keys to using dot separated format
- added support to override freeq url from workspace preferences
- added GEL controls: forEachIndex, forRange, filter
- enforced max-width on preview table columns in expression preview dialog
- added preservedAllTokens option to split GEL function
