Error using local artifact if origin has hyphen

[GregSloan]

When setting artifact_name in the provider, if the origin has a hyphen, the package ident gets incorrectly parsed.

e.g.

origin = "my-origin"
package name = "my-package"

the package ident should be: my-origin/my-package/[version]/build]
instead it gets parsed to: my/origin-my-package/[version]/[build]

Possible solution:

• Require "package_origin" to be set and use it to parse the pkg_ident correctly

I think I'd like to also suggest allowing a "use_lastbuild" option to parse pkg_artifact and pkg_ident directly from the lastbuild.env in the results directory.
