Changes with Aloha.Editor 1.0.16

Bugfix SUP-845

The Word content handler now replaces unnecessary new line characters
added by Word with spaces. This fixes bug SUP-845, in which spaces got
lost, because new line characters are automatically stripped when using
the Text/HTML GCN tag part type.

Bugfix SUP-827

When a URL was pasted into the input field of the toolbar
using the context menu, the URL was not stored into the link, unless
a key was also pressed.
This has been fixed now.
