I18n: make workspaces translatable

This makes workspaces more translatable:
- New Workspace menu
  - header
  - preset menus
  - preset entries
- workspace names upon factory file template load
- new workspace name upon workspace addition

To properly translate those names, an extraction function for
workspace names from app templates was added as well.

(Do not do anything when loading a user-saved file!)
