#5 Show tabs in file contents view.

[Polarpig]

Firstly let me say that I'm lost without Regexxer. I
use it on a GNOME project (over 200 files involved) I'm
working on to search large chunks of code for strings
so I can rework the code e.g. when updating parameters
in function calls, make sure all source files are
updated to the new call before doing a make.

But I'd never trust the replace...so I actually end up
using regexxer as a file navigator and editor !

Thus one thing would help, if the file view on the
right could show tabs then this'll help me. Maybe needs
to show like KWrite does with little . . . . or
maybe some -> arrow thing.

(actually showing file numbers will help too but thats
a different enhancement number).
