support 
 inside title attribute

[chrisv-dev]

Subject of the issue

translate filter does not show as newline.

Your environment

version of angular-translate: 2.15.2
version of angular: 1.3.14
which browser and its version: Google Chrome 61.0.3163.100

Steps to reproduce

add a translate filter to the title attribute of an element with multiple lines.
<td title="{{'some text &#10;some more text in a new line' | translate}}">

Expected behaviour

The title-tooltip should be shown and contain a newline. Content should look like this:
some text
some more text in a new line

Actual behaviour

Instead the tooltip content looks like this:
some text 
some more text in a new line

Notes

Using the 
 without the translate filter like below works fine for me:
<td title="some text &#10;some more text in a new line">
