Signal Desktop: v1.14.0-beta.1 Release

New setting: media permission. Desktop now shows a popup dialog when this permission is not granted and the recording for a voice message fails.

Auto-scroll to selected conversation when they reorder - thanks @matthiasbe (#2498)

Fixed: Conversation preview would sometimes show already-expired message

Fixed: Upon resume from sleep, notifications would show for already-read messages as they arrived

Fixed: About window didn't include version number (#2485)

Fixed: Idle detector would never turn off, slowing down app (#2487)

Dev: - Minor documentation cleanup - bug templates, readme, etc. (#2507) - Update conversation's last message whenever it is opened - Add missing timer option localization strings - Make all OS menus localizable - Handle timer updates along with group updates - Add 'newmessage' event handler to Conversation for reliability - Debug log, settings and media permissions popup are all now in separate windows - Pulled latest translations from Transifex
