Bottom Error Panel and Inline Error

[n3tr]

We can get error stack for bold compile error and component runtime error then format to readable text. mount a ErrorComponent would be a good idea.

Take a look at https://github.com/stacktracejs/stackframe, or https://github.com/csnover/TraceKit for normalize error text

Also make better Bottom Console Panel like in Xcode Panel and allows user to toggle open/close panel.
