adding support for source, stack, and script list outliners.
moved breakpoint related status display()s from handlers.js to here, to that you get console feedback when you set a breakpoint with the UI.
moved initDebugger() and attachDebugger() to the top of the file.
add setCurrentFrameByIndex(), clearCurrentFrame(), getCurrentFrameIndex(), and getCurrentFrame(), migrated code that accessed console._currentFrameIndex to these functions.
make setBreakpoint() smarter (it doesn't blindly clear any breakpoints before setting the new one anymore. that spewed extra "clearing breakpoint" "setting breakpoint" messages. now we scan the breakpoint list ourselves for dupes.)
