v0.18.0

Added

• commands in, clone and manual will show a new "None" option on the projects list on the
  interactive mode if the workspace allows time entries without projects.
• config allow-incomplete allows the user to set if they want to create "incomplete time entries"
  or to validated then before creation. Flag --allow-incomplete and environment variable
  CLOCKIFY_ALLOW_INCOMPLETE can be used for the same purpose. by default time entries will be
  validated.

Changed

• commands in and clone when creating an "open" time entry will not validate if the workspace
  requires a project or not, allowing the creation of open incomplete/invalid time entries, similar
  to the browser application.
• newEntry function changed to manageEntry and will allow a callback to deal with the filled and
  validated time entry instead of always creating a new one, that way same code that were duplicated
  between it and the edit command can be united.

Fixed

• no-closing configuration was removed, because was not used anymore.
