New F#-mode for Emacs

Two years later, I finally released a new version of fsharp-mode for Emacs. It contains many bug fixes, and new great feature.
The F# mode for Emacs is two years old, and has been downloaded more than 1,000 times. Several users have sent me emails and even a few patches. It's now time for an update.
If you haven't tried it yet, here are the main features:
- Syntax highlighting.
- Indentation. The mode knows where blocks begin and end, and tries to correctly indent your code.
- F# Interactive support. You can easily send your code to fsi and get the result.
And here are changes since the last release:
- The infinite loop with the indentation of "else" (and some other keywords) is removed! I think that was the painful problem with the F# mode.
- The paths to fsi.exe and fsc.exe can now have spaces. This makes the installation on Windows much easier. Thanks to Jens Horstmeier!
- When you send an expression to fsi, error messages now display the real location in your source code (instead of "stdin").
- Error messages from fsc.exe are now parsed correctly, so that you can use next-error functions (C-x` by default).
- Error messages from fsi.exe are also parsed. The interactive buffer now uses compilation-minor-mode to highlights errors.
- Improve default key bindings.
- Update the graphical menu bar to make it more user-friendly.
- Fix coloration issues. In particular, Caml-style comments are correctly handled, even when nested and over multiple lines.
- "Old-style backquotes" warning from Emacs 22 is removed.
- Fix the eval region function when it ends by a comment. Thanks to Diego Echeverri!
- Improved README file and instructions.
- Various other fixes and cleanups.
It is important you use a recent version of Emacs, as it fixes a few problems. I recommend you to look at the README file for a complete description of key shortcuts. For instance, you'll learn that Alt + Enter automatically adds the ";;" before sending the expression, in the interactive buffer. Now, get fsharp-mode 0.3!
