TODO

Sandboxing of ghci
UI redesign
Case of multiple errors being returned isn't handled
Move to websockets and remove use of a sentinel
Get inspector working...
Get autocomplete working...
Get haddock documentation working...
How to handle 'getChar' and related...
Move to Hails so users can write plugins...

DONE

Sessions need to timeout
Empty string can be sent to server... (should be a '\n'?)
Once JS has sent string it shouldn't allow editing of that line.
Errors aren't formatted properly
