Update docs

* [runtime] Make it possible to restore old drag behaviour on windows with window.wails.flags.deferDragToMouseMove

* [runtime] Use deferDragToMouseMove as new default

This enhanced version should work well in all cases for Windows:
- No lag/delayed start of dragging
- Double-Clicks and Single-Click events still work in JavaScript on elements

* [docs] Add changelog
