The "Hide menu bar" option is only applicable to Windows and some Linux distros,
where the menu bar is attached to the Signal window. Therefore, this commit
ensures that it doesn't show up on MacOS. It includes a setting,
isHideMenuBarSupported(), to control the option's appearance. This
commit also includes the tests to make sure isHideMenuBarSupported()
works correctly.
Fixes#2705
* Conversation List Item: timestamp bold only when convo has unread
* Preserve the positioning of overlays on re-entry into convo
* ConversationListItem: Handle missing and broken thumbnails
* Shorten timestamp in left pane for better Android consistency

But not if it was from a sync instead of from you or from a contact.
* Make links in quotes the same color as the text
* MediaGridItem: Update placeholder icon colors for dark theme
* Ensure turning off timer shows 'Timer set to off' in left pane
* ConversationListItem: Show unread count in blue circle
* Add one pixel margin to blue indicator for text alignment
* Ensure replies to voice message can bet sent successfully
Biggest changes forced by this: alt tags for all images, resulting in
new strings added to messages.json, and a new i18n paramter/prop added
in a plot of places.
Another change of note is that there are two new tslint.json files under
ts/test and ts/styleguide to relax our rules a bit there. This required
a change to our package.json script, as manually specifying the config
file there made it ignore our tslint.json files in subdirectories
For an easier implementation, we change our original definition of
`initializeAttachmentMetadata`. This means we have to re-run it marked as
version 6 and mark schema version 5 as deprecated as its definition has changed.
When indexing message attachment metadata using numeric indexes such as:
```javascript
{
conversationId: '+12223334455',
received_at: 123,
attachments: […],
numAttachments: 2,
},
{
conversationId: '+12223334455',
received_at: 456,
attachments: [],
numAttachments: 0,
}
{
conversationId: '+12223334455',
received_at: 789,
attachments: [],
numAttachments: 1,
}
```
It creates an index as follows:
```
[conversationId, received_at, numAttachments]
['+12223334455', 123, 2]
['+12223334455', 456, 0]
['+12223334455', 789, 1]
```
This means a query such as…
```
lowerBound: ['+12223334455', 0, 1 ]
upperBound: ['+12223334455', Number.MAX_VALUE, Number.MAX_VALUE]
```
…will return all three original entries because they span the `received_at`
from `0` through `Number.MAX_VALUE`. One workaround is to index booleans using
`1 | undefined` where `1` is included in the index and `undefined` is not, but
that way we lose the ability to query for the `false` value. Instead, we flip
adjust the index to `[conversationId, hasAttachments, received_at]` and can
then query messages with attachments using
```
[conversationId, 1 /* hasAttachments */, 0 /* received_at */]
[conversationId, 1 /* hasAttachments */, Number.MAX_VALUE /* received_at */]
```
Split out test-specific and general utility react components too.
And moved our test/legacy* files for the Style Guide into a styleguide/
subdirectory of test/.
I think we'll be able to live in this directory structure for a while.
