Some fixes based on feedback from Hans Petter Langtangen.

build(): Fix the logic here for calculating fallbacks if the dbfile
isn't parseable.

main(): Fix the semantics for -d/--database; this should override any
database value found in the .pynche file.

Update some comments, and author contact info.

Bump to v1.4

Whitespace normalization.

 Pynche is based largely on a similar color editor I wrote years ago for the
-Sunview window system.  That editor was called ICE: the Interactive Color
+SunView window system.  That editor was called ICE: the Interactive Color
 Editor.  I'd always wanted to port the editor to X but didn't feel like
 hacking X and C code to do it.  Fast forward many years, to where Python +
 Tkinter provides such a nice programming environment, with enough power, that
 I finally buckled down and implemented it.  I changed the name because these
 days, too many other systems have the acronym `ICE'.
 
-This program currently requires Python 1.5 with Tkinter.  It has only been
