Issue description

Current behavior:

I saw in https://github.com/akveo/nebular/blob/master/src/framework/theme/components/chat/chat-message-text.component.ts#L15 that the date input into nb-chat-message is always piped into shortTime. This is confusing if the messages span multiple days. Can something like datePipeFormat: string (https://angular.io/api/common/DatePipe#pre-defined-format-options) be added as an input as well?

Expected behavior:

The chat messages would display the date as well to prevent confusing over messages spanning multiple days.

Steps to reproduce:

Add messages to nb-chat-message where the dates span multiple days.

I want it too.

It should also have the ability to scroll up and load more messages.

Also, I am struggling to order the messages by date ascending. The UI somehow always orders it by message date descending. Any ideas?

[rhuang]

@adarshmenon You have to sort the messages yourself by the date.

For my own perpose I change those lines of code and publish @nebular/theme to our own npm registry.
