Subject: [PATCH 15/76] Add bg+powerline background blend behavior

When a with bg is selected, the cell's regular background will be blended
with 50% opacity selectionBackground in order to retain the bg color info
as well as getting the color to change and getting decent contrast.

This commit also fixes a terrible, nasty bug where the standalone shared
renderer tests were causing the terminal to open multiple times and not
get the WebGL addon activated the second time. So some tests were actually
testing the DOM renderer :o

Fixes #4918

 ```bash
-npm install xterm

 To start using xterm.js on your browser, add the `xterm.js` and `xterm.css` to the head of your HTML page. Then create a `<div id="terminal"></div>` onto which xterm can attach itself. Finally, instantiate the `Terminal` object and then call the `open` function with the DOM object of the `div`.

 These should generally be stable, but some bugs may slip in. We recommend using the beta build primarily to test out new features and to verify bug fixes.
