Short description of error

Three name convention warnings when you switch the library in the materials library vx addon.

Materials Library VX addon comes with Blender and is activated by default.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Open Blender, switch to Materials tab, go to the Materials Library VX addon. Switch to another library. Watch the console.

There is one panel and two menus which doesn't follow the name convention so far. And the two menus had a unnecessary bl_idname, which gots used to display them in the panel. While you can display the menus with the classes names already.

I tried to fix it by myself, and so far the addon is working fine, and doesn't throw an error anymore. So my solution seems to follow the name convention now.

Whoops, better check the init.py, i made some usability changes at it, and forgot to revert them for this report. I included the Preview element into the addon, and made the preview and assign buttons bigger and easier to access. Both has nothing to do with the error message reported here. But maybe you find it useful ...
