hex printing from ishell

[jabraham17]

Right now there is no way to print anything but as a decimal integer from the control interface. It would be very useful to be able to control this.

Possible design ideas

• -control 'dump $pc /x'
  • this is clean but will complicate the lexer
• -control 'dump/x $pc'
  • this is also clean and will only slightly complicate the lexer
  • also has the advantage of being similar to gdb, so famailar
• -control 'dumpx $pc'
  • doesn't complicate lexer
  • clean implementation
  • BUT requires a new keyword and new parse rule for it
• others?

This should also support some kind of Unsigned option, which forces unsigned evaluation
