Fixing selectLocation Madness

At present the selectLocation method is trying to do too much, specifically because the auto-pretty-print logic is a bit weak:

if (
  prefs.autoPrettyPrint &&
  !getPrettySource(getState(), sourceId) &&
  shouldPrettyPrint(selectedSource) &&
 isMinified(selectedSource)

The Firefox debugger has undergone a massive rewrite in the last two years, moving away from old Mozilla-specific technologies like XUL etc, to more modern technologies like React, webpack and babel.

[Babel][babel] is a tool for compiling Javascript into Javascript. It generates an [Abstract Syntax Tree (AST)][ast_wiki] which can be transformed, transversed or manipulated in various ways for use. Babel and AST's have played a major part in growth of the modern web tooling ecosystem.

Over the past year, we have used babel extensively in building the debugger, from disabling non-executable lines so breakpoints cannot be set to highlighting out of scope code and much more.

I felt it would be cool to write a couple of blog posts, documenting some of our coolest use cases and looking into some debugger internals as we go.
