MSBuild fails when total error limit is reached

[PShchegolevatykh]

Hi Ben,

Thank you for the library. It's been working great except one thing. When the error amount exceeds default it fails the build with an error:

Total JSLint: error limit reached: 1001

Currently, I'd prefer not to fail the build at all. I'd like to show everything as warnings. I set "output": "Warning" in my JSLintNet.json and in my target I changed Error block to warning like so:

 <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Warning Condition="!Exists('..\..\packages\JSLintNet.MSBuild.2.3.0\build\JSLintNet.MSBuild.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\..\packages\JSLintNet.MSBuild.2.3.0\build\JSLintNet.MSBuild.targets'))" />
  </Target>

It still shows "Total JSLint: error limit reached" as an error. Is this a bug?
