openmethods 1.3.0

[Jean-Louis Leroy]

This release implements support for function attributes, except 
for `pure`. User-defined attributes on methods and method 
parameters are also supported.

It is no longer necessary to call `updateMethods` explicitly, 
except after dynamically loading or unloading shared libraries.

The internals got a major cleanup. All the mixin generating code 
has been moved to a separate set of modules, which I plan to 
contribute to the bolts library.
