Add new variable "ivy.settings.base.url" which is independent from the way the settings file is loaded/included
---------------------------------------------------------------------------------------------------------------

                 Key: IVY-607
                 URL: https://issues.apache.org/jira/browse/IVY-607
             Project: Ivy
          Issue Type: Improvement
          Components: Core
    Affects Versions: 2.0.0-alpha-2
            Reporter: Maarten Coene


The value of this ivy.settings.dir variable depends on how the settings are loaded.

For instance:

{code}
Ivy ivy = new Ivy();
ivy.configure(new File("C:/test/ivysettings.xml"));
{code}

will set the value of the ivy.settings.dir to "C:/test".
However, if you configure Ivy like this:

{code}
Ivy ivy = new Ivy();
ivy.configure(new File("C:/test/ivysettings.xml").toURL());
{code}

you'll end up with an ivy.settings.dir variable with value "file:C:/test"

This makes a big difference in the way you can use the ivy.settings.dir variable!
For instance, a lot of the Ivy junit tests will fail if we configure Ivy with the URL instead of the File.

Another example, consider the following ivysettings.xml file:

{code}
<ivysettings>
<include url="${ivy.settings.dir}/ivy-shared-resolver.xml"/>
</ivysettings>
{code}

This will only work if you configure Ivy with an URL. If you configure Ivy with a File, it won't work anymore, unless you use the "file" attribute to include the other settings file, or add "file:" befoire the ivy.settings.dir variable.

To solve this problem we could introduce a new variable: ivy.settings.base.url which points to the same path of ivy.settings.dir, but which is always an url and can always be used as value of the url attribute.
