I removed tkinter imports from views_tkinter_tree, was that it?

[azazellochg]

Now I see this is about file handlers.. not sure what can be done here..

[pconesa]

Don't worry, this is to remember to do it in a different way.

Currently, the situation is:

1.- File handlers are provided by plugins
2.- They need to be registered as soon as possible...currently at plugin's init which end up importing tk in the import casacade.
3.- This is means that tk should be in the installation always, which is true, expect when you remove it when fixing fonts.

I've changed de documentation of the fix font to be a single command

In any case, we should find another mechanism to register the filehandlers triggered by the GUI.
