CPURL

[Francisco Tolmasky]

Cappuccino has up till now used string paths instead of actual URL
objects like Cocoa. With the following commits this has changed:

I believe I have made all the appropriate changes, but if you run into
any errors with your code that uses URLs, please let me know. In
theory, this change should be somewhat if not completely transparent,
as the main input for URLs, CPURLRequest, is "nice" and auto converts
string paths to URLs for you:

[CPURLRequest requestWithURL:[CPURL URLWithString:@"http://
something.com"]]

is equivalent to

[CPURLRequest requestWithURL:@"http://something.com"]

CPURL is still not completely finished, but it should help out
greatly. For example, if should make it much easier to compare URLs ("/
x" may be the same as "whereveriam/x"). It also makes it easy to get
at parameters like scheme, protocol, query string, etc.
