Add Visual Studio 2015 support

[Ubikuity]

I added the following code to "source.extension.vsixmanifest"

      <VisualStudio Version="14.0">
        <Edition>Ultimate</Edition>
        <Edition>Premium</Edition>
        <Edition>Pro</Edition>
        <Edition>IntegratedShell</Edition>
      </VisualStudio>

I compiled it and I installed "GitSccProvider.vsix" into Visual Studio 2015 RC.
=> The extension is partially working:

• The "History" window and the GitExtensions/TortoiseGit operations are working
• The "Pending changes" window doesn't work: it doesn't show up (and there is no error message).

Do you know how to fix the problem? Do you plan to support Visual Studio 2015?
Thank you.

Sorry. The "Pending changes" window is working in Visual Studio 2015.
I just realised the "Pending changes" window opened on the left corner my second monitor :-)

I created a merge request to add support for Visual Studio 2015:
#121

Update: when I open "Pending changes" window, sometimes I get an error message.

I think what you are seeing has to do with the feature "CodeLens indicators for all types of files":

The editor might be trying to put that information in the text view that appears in the pending changes window.
