Backport for TYPO3 8.7: PageLayoutView - Allow to disable copy- / translate- buttons

README.md

This patch backports the new feature to disable copy- / translate- buttons from TYPO3 9.x to TYPO3 8.7

See https://review.typo3.org/#/c/52345/ for details.

The localization actions "Translate" and "Copy" are then toggleable by PageTS and UserTS.

mod.web_layout.localization.enableCopy = 1
mod.web_layout.localization.enableTranslate = 1
