release dulwich 1.0.0

From here on, Dulwich will not break backwards compatibility until 2.0 - although we may print DeprecationWarning when using deprecated functionality.

Micro releases (1.x.y) will be reserved for important bugfixes.

Major releases (1.x.0) will introduced new features and functionality, without breaking backwards compatibility.

Really happy to finally get to this point :-)
