fig-0.1.5 released

[Matthew Foemmel]

I somehow managed to skip version 0.1.4 when I did the release, so
here are the changes since 0.1.3:

* The default fig file name is now "package.fig" instead of ".fig"
* When using the ssh protocol, the server must now have fig installed
and in the default PATH. To test your setup try running "ssh localhost
fig -h".
* You can now specify resources/archives/set/append options on the
command line when publishing packages, instead of using a fig file.
For example, to install jruby-1.4.0 in the shared repository you could
do something like:

fig --publish jruby/1.4.0 --append PATH=@/jruby-1.4.0/bin \
--archive http://jruby.kenai.com/downloads/1.4.0/jruby-bin-1.4.0.tar.gz

* Added a "--clean" option to delete packages from the local
repository. If no version is specified, all versions will be deleted.
For example:

fig --clean jruby/1.4.0 # deletes one version
fig --clean jruby # deletes all versions
