This solves the old signed vs. unsigned problem and allows for more
bases than just 8, 10 and 16, as well as auto-detection of the base (if

Also renames +[OFHTTPCookie cookiesFromHeaders:forURL:] to

This requires passing a domain and defaults the path to /. file: [fe9eb6c85d] check-in: [f36f9bed02] user: js, branch: trunk, size: 9542 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [ef24e84f97] check-in: [4af49a13c3] user: js, branch: trunk, size: 9168 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [ee6a333bc6] check-in: [44f45c2e35] user: js, branch: trunk, size: 9159 [annotate] [blame] [check-ins using] [diff]
