Subject: [PATCH] build: add i18n-merge-openwrt-19.07

Support backporting translation strings from 19.07 to 18.06 by adding a script for that.

Targeted workflow is:
1) sync 18.06 to apps
2) backport 19.07 translations
3) re-sync 18.06 just in case
4) backport master translations
5) re-sync 18.06 just in case
