Remove integration tests concerning Evaluator
Update command-line tests

The usage message is printed on errors, so they've been updated to
reflect this.
Remove report_results.sh since evaluator has been removed
Rename libs to lib
Add configuration files for building with autotools

Running autogen.sh will run aclocal, automake and autoconf.  I followed
the guidelines at
http://www.mono-project.com/Guidelines:Application_Deployment
for structure of the install program.

fsharp-refactor is installed in PREFIX/bin and everything else is in
PREFIX/lib/fsharprefactor.
Required files for autotools

COPYING is currently empty, I'll decide on a license soon.
ChangeLog is also a required file
