Fix highlight in normal mode
Changed unsigned types to signed ones
Option --type replaced by -b.

This way we do not show explicitly signed/unsigned nature of
variables. This way it will be more acceptable if arithmetics will be
signed but shift operation will be explicitly unsigned.
Tune up type enforcement policy

If intval is written in dec - increase type size after MAX type
limit. If intval is hex then treat it as unsigned - increase size only
after unsigned limit or after certain width.
Little cleanup
Default results printout is horizontal (comparative).

To print results one after another traditional -l|--list may be used.
