line terminators when:
a) running under windows, and
b) the file on the disk (when DrRacket first opens it)
contains all CRLF line endings.
In all other situations, the file is saved with LF terminators.
Before this commit, DrRacket would always use the platform-specific
convention, regardless of the original content of the file.

Took the inspiration for the list from the keybindings
available in Scheme mode in Emacs.

I originally picked "under" as the preposition to go before
a platform name, but obviously you should build "on" a
platform, and "under" suddenly annoys me. The choice of "on"
is now codified in the documentation style guide. Meanwhile,
"Unix" insted of "X" seems more clear and consistent in the
`racket/gui' docs.
More usefully, this patch also fixes a few out-of-date
platform-specific claims.
- improved the drawing speed in mrlib's graph pasteboard
by caching the background arrows (optionally; only turned
on for the module browser. in redex, this probably won't
speed anything up so it isn't used)
- added a search feature to the module graph to help find
dependencies; type in string and some of the graph changes
color
