Added essential grid view cell editing support, accessible from the Schema Explorer by double-clicking on a table (normal query grids remain read-only.) Cell editing currently is not type-aware but does check for constraints. Nullable cells can be set to NULL by completely deleting their content, while non-nullable cells will be set to an empty string when this is performed. Finer controls will be implemented in future versions. Adopted new build numbering to indicate major test-ready changes through the development process. Current commit version: 0.7.0.7.
