[ANN] release: a "which" command written in ruby--very useful for windows users at least

Announcing the release of "ruby which"[1]

README:
Ruby-which is the linux "which" command re-written in ruby [and
windows-friendly].

-- An executable locator (which command) for windows that actually works!

There seems to be a lack of a "which" command for windows that
actually work--they sometimes skip batch files entirely [batch file?
what's that?] or don't list extensions, leaving you in doubt. Despite
running "which yyy" you never know what you're really running when you
next run yyy in the command line--is it yyy.exe or some other yyy.bat
that wasn't reported by "which"?

Try it--you might really like it.

To install:

   C:\>gem install rogerdpack-whichr

   C:\>whichr executable_name_here [extension can be included, but is optional]

   usage:

   C:\>whichr ruby
   higher in the list will be executed first
   ./ruby.bat
   C:/Ruby/bin/ruby.exe
   c:/cygwin/bin/ruby.exe

Enjoy.

$ gem which nokogiri
(checking gem nokogiri-1.3.2 for nokogiri)

# incidentally, it's TTY smart:
$ gem which nokogiri | cat

Nice. I've noted the usefulness of "gem which" in the README file now.

Also have updated whichr to v 0.1.2 now to incorporate a few of Alexey
Borzenkov's suggestions.

ChangeLog:
respect's ENV['PATHEXT'] now on windows
