cleanup: Mostly comments

Should not change anything.

bugfix: screen resize wasn't propagating to other pages.

Need to resize all pages, when terminal is resized.  Otherwise, when we
switch pages, they will have the wrong size.

bugfix: ruby 1.9 has a different require statement for local files

This bug only affects development, and has no impact on installed
versions.  The jedi.rb test code used "require 'xxx'", while ruby 1.9
seems to want "require './xxx.rb'" instead.  Ruby 1.8 seems happy with
that.  Again, does not affect single-file or installed version.

feature: better handling of regexp search and replace

Can now use ()() to specify parts of the regex match.  Much more
powerful and flexible.

bugfix: "print" instead of "puts"

Was putting an ansi escape code to the screen rather than printing it.
Only difference is the extra newline.  This only affects the
show_cursor method.

	modified:   src/antsy.rb
bugfix: Switch default to: don't show cursor.  Only show it for getch.

This keeps us from seeing the cursor fly around the screen.

	modified:   src/antsy.rb
cleanup: cursormode is now a token (not a string)

Requires a change to the example config file.

bugfix: nmuloc mode was crashing when off edge of screen

highlight() must check to see if we are off the edge. It has to be done
there, because we need to know what screen position we are at (as
opposed to buffer position).
