Set and reset action version immediately before and after it is published

[js07]

When publishing actions current:

1. the version of every action is set to a temporary "dev" version
2. then each action is published synchronously
3. the version of every action is reset to its previous version

Instead, so there is a much smaller time interval between writes to each action file, publishing actions should:

1. For each action being published, synchronously
   a. set its version to a temporary "dev" version
   b. publish the action
   c. reset its version to its previous version
