#253 FilterBuilder focus problem

[Omry Yadan]

FilterBuilder is very nice, but I encountered the following problem while working with it:
when a text field was in focus (most of the time without the my intention) and I used the keyboard (ctrl+v) to paste a filter, the text-encoded form of the filter was injected into the text field.

currently the clipboard works with strings only, and this is the problem.
if the data will encoded as binary in the clipboard text fields will not accept it).
