Add new editable column for naming the purpose of the bricklets

[shyukri]

Hello,
In complex setups with multiple bricks/bricklets add the option for the user to give the devices meaningful comments so it's clear which device you're using.
If you can give any hints for the places required for the change i can take a look.

Where would you want to show the information? In the overview of the "Setup Tab" or in the tab of each Brick/Bricklet?

If it is shown for each Brick/Bricklet we could put it somewhere at the top under the "More"-button?

"Setup" tab is my personal preference :)

Take a look at the update_tree_view function, you would have to add it there: https://github.com/Tinkerforge/brickv/blob/master/src/brickv/mainwindow.py#L861

If you want to make the data persistent, you may take a look at how we save the ip addresses that you can connect to. You probably would have to save a tuple of the UID and the description. That then can be read on startup again.
