Project creation UI workflow requires validation

[owenbyrne]

The project creation workflow through the UI (Add Project view etc.) requires validation as it's currently possible to rm -rf the ~/.cruise/projects directory by adding a blank project.

To reproduce: 1 - Add Project view 2 - Click create

Params should look like:

     "project"=>{"name"=>"",
     "source_control"=>{"repository"=>"",
     "source_control"=>"Git"}}}

SourceControl.create checks for nil instead of blank, so no exception is raised. raise ArgumentError, "options should include repository" unless scm_options[:repository]

Project.create catches an exception trying to checkout a local copy, given there's no project name it rm -rf the project directory in the rescue.

```FileUtils.rm_rf "#{dir}/#{project.name}"````

This is definitely alarming; thanks for the report. Taking a look now.
