Refactored the Rakefile to more cleanly run emacs tasks.

* Added clean task to remove elc files.
* Added run to prevent backtraces on failures.
* Refactored to top level emacs function (no longer loads tests).
* Added emacs_test that calls emacs w/ tests.
* Wired up default to clean, test, and then compile.

Sorted all defcustom sexps. Easier to find things.

Now I need to rename some stuff for consistency and deprecate the old.

Trying to make erm server more fail-proof.

It gets INCREDIBLY annoying when erm can't parse nor close a buffer.
This should make interrupted processes while closing a buffer work.

That said, there is still a lot in here that hangs up erm in a way I
don't understand yet.

Improve debugging output so I can see what face it maps to.

better movement

Make erm more resilient towards errors.

Still not perfect. Need to figure out odd encoding errors that seem to
want me to be in binary mode. Need to make it better about not bugging
me if I've opened and killed a bunch of buffers quickly. The errors
from killing of buffers in particular are annoying. Makes using macros
tedious.

Add some tests for bug #78. One passes, one fails.

oops! forgot input file.

Slight improvement of tests.

Hooked up test:all to default
