Make Return Types and Deploy Params More obvious

[saltyskip]

Currently it has the raw integer values, and it is not possible to know what this translates to (String, Int, etc.)

It would be nice to show the type in plain text format instead of the hex code

This is what happens when you work with nerds hahahah you're right, we will fix that soon enough ;)

@saltyskip and @igormcoelho, should we let both:

• ff - void
• 02 - string
• 04 - beer
  etc

Or just the type?

[saltyskip]

+1 for both

Done, thanks @saltyskip.
