While doing testing for the new version of Foobar2000 Copilot v1.3.0.0, I encountered some small issues relating to album art, and so ended up making a few more modifications to the foo_controlserver component.

The new version of foo_controlserver is v1.1.4. I've uploaded this version along with its full source code to GitHub.  The component is backwards compatible with the original version v1.0.2 and will work with all versions of Foobar2000 Copilot.

For instructions on downloading and installing it in Foobar2000, see :  foo_controlserver plug-in install

At this point, I've completed most of my testing of Foobar2000 Copilot 1.3.0.0 and it is performing well, so I'm close to getting it released to the Microsoft store. I'll post here when it is available.
