Display line breaks

**Is your feature request related to a problem? Please describe.**
Currently, Element Android 1.0.7, line breaks are not displayed. So this text
```
Erlauntza
Alde:
-Alegoria
```
will be displayed as
`Erlauntza Alde: -Alegoria`

To sum up, the messages on Element strip line breaks and inline spaces.

**Describe the solution you'd like**
The logical display would be to maintain the original structure, only stripping initial and final spaces.
But all the line breaks and inline spaces should be displayed.

The problem with this can come with the lack of message-boxes on Element (unlike most message apps)

**Additional context**
Here can be seen an example of the current behaviour. The top message is how it is displayed. The bottom, how it really is (via editing)
