Module-Build 0.09

on Perl CPAN

The 'distdir' action wasn't deleting the distribution directory
before building it again. This meant that, say, if you did 'Build
disttest' then 'Build dist', you'd end up with a blib/ directory
in your distribution. I actually had this happen for version
0.08, and it's not nice to distribute a blib/ on CPAN.

We now keep track of the 'base_dir', i.e. the top-level build
directory, so we can change back into it if we change out of it.
This necessitated a cwd() method, which uses the Cwd.pm module.
I'm aware of Cwd's limitations, particularly under taint-mode, but
I don't know a way around using it here.

The 'dist_dir' action now changes back into 'base_dir' directory.

We now do write_config() inside the create_build_script() method,
not inside the new() method.

Simplified the find_version() method, and improved its error
messages.

Renamed module_name_to_file() to find_module_by_name(), and added
a parameter specifying the directories to search in. Previously
we searched in 'lib' and @INC, which wasn't correct in all
situations.

Patched the docs to change "Build test" to "./Build test"
