Let user choose created repository type
The following patch lets a user choose what kind of repository they want reposman.rb to create, by adding the repository with "create_me" or "file:///create_me" as the url/path. Currently it supports CVS, Subversion, and Git.
Probably this should be done more prettily, having a checkbox to have
the repository be created, rather than putting "create_me" in the text field, but I'm a Rails newbie, and that looked like a harder change :-).
