Update git submodules

* Update docs/submodules/qtip from branch 'master'
  - Refactoring workspace related commands to `project` group

    - renamed `workspace` to `project`, which is more accurate
    - group create/setup/run/teardown into `project`
    - shortcut for project commands, e.g. `qtip create` <=> `qtip project create`
    - even shorter command alias, e.g. `qtip s` => `qtip setup`
