Finds binaries in the WIX_HOME folder if that environment variable's set.
Documents support for the WIX_HOME environment variable setting.
Bumps the version to 0.1.0.

Now that we support WIX_HOME, this is as real as it's ever going to get.
Bumps the Rake dependency to 10.0.3 since that's what's out now.
Merges branch 'support-wix-home-variable' into master.

This adds support for looking up the path to the WiX binaries in the
WIX_HOME environment variable. It also bumps the version to 0.1.0 and
ups the Rake dependency to 10.0.3.
Removes support for harvesting empty directories.

Heat does a poor job of generating valid CreateFolder entries when
you use the -ke and -ag flags together. I'd rather have auto generated
guids than empty folders at the moment.
Skips generating file copy tasks for files that don't move.
Merges branch 'make-no-src-copy-work' into master.

This makes the no source copy option (where you put files in wix/src)
work correctly. Files whose source and destination match don't generate
file tasks. It also removes the harvesting of empty directories, since
heat doesn't do a good job of both auto generating GUIDs and keeping
empty diretories around at the same time.
