Trying to use web view to display the html;
Chaniging the UI to have TextView instead of TextField... also side outline view is more like Finder’s side view;
Improved textview to enter sqlite queries;
Doesn’t try to save the file anymore; Removed font and colour toolbar item;
Left outline view updates properly;
Fixed few UI issues and added some features

Fixed:
- closing will not ask to save, and autosave is disabled
- removed Page stepper and unused code
- removed words completion feature
- added pragma statments
- moved opening database into function
- using alt+enter, multiple statements can be written — having the text insertion point at a query and pressing enter will execute that query
- result tableview header identifier used to be index of column title, now, its the column title itself (this will help when editing field from tableview is allowed to save changes in the database).
- private ivars starts with underscore
Added DBManager class for sqlite, but didn’t integrate with other code.
Create README.md
Added basic syntax highlighting and other features

Added
- Console view for query and it’s output including error message
- basic (dumb) syntax highlighting of sqlite queries
