Incompatible with FindBar Tweak

[Quicksaver]

When (if) you get back to developing barlesque, one of your users has brought to my attention a few problems that arise when using Barlesque and my add-on FindBar Tweak at the same time, namely when the option "Move the Findbar to the top" is enabled.

I will release a quick fix of FindBar Tweak that is able to deal with the add-on bar positioned on top, but even this is not perfect and the other options I can do nothing about on my end because most of your code is done in javascript and I'd have to replace many of your functions for everything to work.

So when you do resume working on this, please let me know so we can figure out the best way to deal with this incompatibility. Initially I'd suggest ignoring the height of the findbar when it is positioned on top (check for a "movetotop" attribute).
