Change default browsers

I decided that any big changes in Browserslist should be approved by >50% Browserslist users.

Suggestions:

1. Add not dead query to default browsers. It is a new query of dead browsers. Dead browser is a browser with less than 1% global market share and no security updates or no new minor/patch releases for last 12 month. IE 10 will be a dead browser. Maybe Blackberry browser as well. I will maintain the list of dead browsers manually.
2. Decrease market share limit from >1% to >0.5%. It will add android 4.4, chrome 61, chrome 49, ios_saf 10.0-10.2, ios_saf 9.3. The most important here is chrome 49, because it is the last Chrome with Windows < 7 support.

What do you think? Are you agree with this changes?

Notice about other 3.0 changes:

• BlackBerry 10 and BlackBerry 7 will be added as dead browsers as well.
• I plan to remove >1% in US queries support in a client-side version of Browserslist. Country usage statistics takes 155 KB in the bundle and used very rarely. It will be still possible to use country statistics by stats: require('caniuse-lite/…'). This change will reduce Autoprefixer size for tools like CodePen.

3,0 was released. Let’s update dependencies in our project (I will release a major update for Autoprefixer, but it is up to you).
