Signal Desktop: v1.15.0-beta.4 Release

Fixed: Application does not start up on Linux w/tmp mounted as noexec

Fixed: When attempting to record voice note with media permission disabled, popup would be blank

Fixed: Replies to locally-sent voice message would never send

Fixed: With message details or media gallery open in a conversation, switching away from that conversation and coming back would cause rendering to go awry

Left pane: - When conversation is unread, show unread count in blue circle - Timestamp is bold only when convo has unread messages - Timestamp has been shortened to better use space - When sorting conversations, match Android by including timestamps from expire timer changes - Fixed: Timer shows 'Timer set to s' instead of 'Timer set to off'

Media Gallery: Show thumbnail for files that don't have thumbnails

Quotes: Make links the same color as surrounding text

Update localization strings
