doc, debugger

• Update examples according to new debugger output (info added, lines reordered).
• Replace x = 5; by explicit global.x = 5; to stress the intent to create a global variable (needed for access from debug REPL).
• Add break marks (>) in output according to real output.
• Update also the Inspector example.

Some updates are done due to previous changes in test/fixtures/break-in-module/main.js and test/fixtures/break-in-module/mod.js files.
