New Dock With Preview

A new Dock style in Dark Mode with windows preview.
Had redesigned follows...
1、float the Dock position and set margin-bottom: 8pt
2、border radius change to 8pt
3、adjust the shadow and add inner-shadow
4、some transparent and blur reset
5、Window Preview —— add document type distinguish and the close btn when cursor hover.
