"Processes" branch is now the "trunk".

The experimental multi-processing support that was being developed in the processes branch is now merged on to the trunk (v140). That is, its official! I've been waiting for this for a long time now. Apart from various bug fixes and other process related stuff already described, here's whats new -

1. New primitives post and process?.
2. New s-expr syntax and functions to work with raw byte data.
3. MAJOR code change to make muSE truly embeddable. This change breaks API compatibility. The new API calls all take the environment pointer as their first arguments so that multiple muSE environments can coexist in the same OS process or thread without interfering with each other.
