/TODO

1* Complete file paths in strings (for require etc)
2* Write docs for using a as library. Probably right after creating a Cocoa client.
3* Add specs for irb/driver/socket, and possibly for bin/dietrb
4* Configurable history file? (:HISTORY_FILE) Configurable number of saved history lines? (:SAVE_HISTORY)
5* Make sure the following formatters work: hirb, awesome_print, and looksee
6* Make sure the majority of the utils in utility_belt work
7* Possibly add copy-paste support as an ext
8* Decide whether or not we need more control for colorizing which could be done with Ripper::SexpBuilder
