PsySH v0.8.4

New:

• Add code argument support to commands. Use this for great justice.
• Add a sudo command. Check it out. I promise you won't be disappointed.

Improved:

• Don't show => null for code with no return value. Because it was a lie.
• Add --grep, --insensitive and --invert filter options to trace and wtf? commands.
• Include previous exceptions in wtf? output.
• Show default values for props in ls ClassName.
• Various and sundry code cleanup.

Seriously. Check out sudo.
