Add -F (Force) and -p (sourcePackage) flags to nicole

As discussed on IRC, we require two options to be added to Nicole:

   -F (Force)
   -p (sourcePackage)

The semantics are as follows:

  -F indicates that, regardless of whether or not a sourceforge or freshmeat project was found with the suggested name, create the product.

  -p indicates that the product listing file will contain a second column which indicates a sourcepackage name that should be associated with that product. All sourcepackages that are related to that sourcepackage name should have packaging table entries added. Example file follows:

  analog analog
  anna anna

Note that -p implies a change in workflow: even if the product listed exists, we still need to check if all sourcepackages listed require adding to packaging. For instance:

  apache apache
  apache apache2

Even though apache will already exist, we should add a packaging entry for both apache and apache2. This also implies that existing products (that were manually entered) need to have all package listings associated.
