Panagement 2 not recognized by default on Linux

[lminiero]

Even when installing the Pagamenent LV2 plugin, the template fails to load it when creating a new session. Manually adding it to a track works instead, so looking at the .ardour file I noticed that there are a couple of properties that need to be changed in the .template file to work, specifically in the Processor element with name="Panagement 2":

1. type="lv2" (the one in the template has type="mac-vst")
2. unique-id="https://www.auburnsounds.com/products/Panagement.html40733232#stereo" (the one in the template has a numeric ID, that I think is the main reason why my setup can't find it)

With this change to the template, it works for me. Of course, manually editing the template in the repo makes little sense, but maybe adding a couple of lines in the README might help those that can't get it to work either (unless some tip is there somewhere already and I missed it?).

Thanks for your great work!
