adding a bluilt in pitch analyzer to the sample track

I think it would be cool for the sample track to have a built in pitch analyzer for tuning of live Instruments like Guitars. The reason for it to be built in and not as a plugin is I think it's silly to have it on all of the tracks when you only need it on the sample track.

How to:
Go to the gear menu click on show/ hide the tunner.

Tunner GUI
#1471 This will enhance the sample track even more. The pitch analyzer should be built into the track not as a plugin this way all sample tracks have it and you don't need waist a plugin spot. When the LMMS pitch analyzer plugin is built It all so can be built in to the audio track editor with a on off button. Both the built in pitch analyzer and the plugin versions should be in LMMS for three reasons.

Reasons this is good:
1. Backward compatibility.
2. When a user is using the audio track editor for recording a user doesn't need anything but the audio track editor window to check the tuning.
3. The plugin version would be great for those who want to use LMMS live and want to check the tuning without needing to open the audio track editor window.

Start by reading this issue and the referenced #1471 to understand the proposed sample-track and plugin approaches. Clarify whether the work includes the gear-menu toggle, the audio track editor, a separate plugin, or all three. Done means an agreed scope and a usable pitch analyzer for tuning live instruments, but the issue does not identify files or tests.
