* Prevent FOUC on startup, use Signal Blue instead
Instead of flashing a white background on startup, the app will show a blue background while everything is loading.
* Make sure tests are rendered on white background
* Use `icon_250.png` as the loading image
* Remove hardcoded 'Loading...' text from template
* Make sidebar non-selectable
* Prevent selection of avatar and context menu text in conversation view
* Make loading view and conversation placeholder view non-selectable
* Make settings view contents non-selectable
Also:
- New schema version 8 with video/image thumbnails, screenshots, sizes
- Upgrade messages not at current schema version when loading messages
to show in conversation
- New MessageDetail react component
- New ConversationHeader react component
UI now in separate renderer:
- the permissions popup
- settings dialog
- debug log dialog
- about window
Couple bug fixes:
- About Window: Fix 'escape' to close window
- Remove outdated dist/copy tasks from Gruntfile
Eslintified settings_view.js
Three locations were changed:
1. a group update, which lists a set of contacts
2. the contact name in the left pane
3. the conversation title
Three new components were added to window.Signal.Components to support
these scenarios, respectively:
1. Emojify
2. ContactName
3. ConversationTitle
Note that there are a number of other places in the app that should be
emojified, but never have been before. Essentially any place that a
contact name might be shown. A non-exhaustive list:
- Show group members
- Show safety number
- Verified change notification
- Disappearing timer change notification
- Contact verification notification
- Quote contact name
