«Safari Technology Preview» && only running application

[a06kin]

Today I began to look for the alfred workflow "find browser tabs"; I came across your repository; Great work man!!!

I don't like the fact that it starts inactive browsers every time when looking for tabs - fixed; And I'm using "Safari Technology Preview" - fixed;

Look at the changes and write your thoughts);

@a06kin Create! Thank you.

But I want you to fix a simple problem. Would you please change paddings of the icon?

This PR attempts to solve two things at once, and it is pending. I opened PR #3 to implement appIsRunning filter.
