v2.4.0

Highlights

• All of tsrc commands can now be run in parallel. Try for instance tsrc sync -j auto.

• tsrc foreach now sets a bunch of environment variables. This allows
  developers to add new behaviors to tsrc without having to change its source code. See
  the relevant guide for more information.

• Augment documentation with more use cases and examples (still a work in progress)

Breaking changes

• Remove tsrc version - Use tsrc --version instead.

• The 'parallel' feature caused the output of some commands like
  foreach or log to change slightly. Hopefully
  tsrc output is now more consistent.

Bug fixes

• Fix crash when running tsrc without any arguments

• Fix crash when trying to clone repositories in some rare corner cases
  (like the destination existing but not being a directory)

Internal changes

• Make all tsrc imports consistent
• Fix error when calling repr on tsrc Errors.
