parallel-test 0.3.2

This minor release improves parallel-test's dependency management:

• Parallel-test no longer includes an implicit parallel-test profile. If the project.clj specifies one, it will be used during parallel-test.
• Parallel-test will check dependencies before launching the child JVM, and ensure that the parallel-test plugin, core.async, and robert hooke are on the classpath. It has default versions for these if unspecified, and, if these are specified it will not add them.
• Implicit core.async updated to 0.4.474
• Tested on dayjob use, and it's equivalent to 0.3.1 for our CI purposes

0.1.1: Update dep logic for lower footprint:

- Instead of a coded in :parallel-test profile, just enumerate the
  deps we need
- Insure they're in resultant project, if absent. If present, keep
  what the user project specified.
- Only deal in the :parallel-test profile if the user has specced it.
- Update the core.async version
