Working for me with 2 local plugins separated by colon

A test case would be nice though, I think we already have some test cases for interpreting other env types in test_config.py (probably should move those to test_environment.py)

[masenf]

This should give us some impetus to expand the plugin API to allow for more interesting integrations, like post_compile to give a chance for custom modifications in the .web directory.

redundant tests can probably be removed from test_config.py now
