#218 Delete collapsed group.

[Lesoň Kořenáč]

When I want to delete collapsed group, only first line is deleted. Is it intended behaviour? If so, would it be possible to add option to allow to delete whole group?

Example:

Expanded text:
+ | <ItemGroup>
| <Reference Include="System"/>
| <Reference Include="System.Core"/>
| <Reference Include="System.Xml.Linq"/>
| </ItemGroup>

Collapsed text:
- | <ItemGroup>

After selecting collapsed text and pressing "delete":
|
| <Reference Include="System"/>
| <Reference Include="System.Core"/>
| <Reference Include="System.Xml.Linq"/>
| </ItemGroup>
