Better support for multiple toolbars

[ChiraChan]

I would like to be able to use multiple toolbars at once, in order to place them around my screen in more flexible ways.

Currently, I managed to do it by opening tablet friend twice, however this behaves rather buggy. It opens both of them in the same place, and to the same layout every time, so I have to manually change one of them. It can require multiple clicks on the tabletfriend tray icon to get them to appear. Then the changed one jumps back to the previous one when I tab into the program they're both set up for, until I disable automatic per-app layouts. This setting also seems to reset the next time I open tabletfriend.

I'd like to be able to open a second toolbar easily by for example right clicking the tray icon and clicking an "new toolbar > [select layout]" option. I'd also like to be able to configure multiple per-app toolbars, and have them actually automatically open all at once, once I switch to that app.
