Language Resource Template - include default language setting as in srx

Hello Studio developers:

For clients working in multiple languages, it would be handy to have:

  • Option to use 'default' language settings in the Language Resource Template as in SRX previously, or
  • Introduce a quick and easy copy rules to all applicable languages, instead of having to re-create the same rule one by one under each source language.
  • Make the LRT file readable outside of Studio, e.g. Notepad++ and ideally importable as well.
