Text gets "buffered" if no text editor is selected, and upon selecting it, it types the text.

How to reproduce:

1. Start Picotron
2. Type something
3. Open up filenav
4. Select the navbar
5. The text appears where you click instantly.

Thanks @Soupster, this is fixed for 0.1.1c

The default textfield gui element (/system/lib/gui_ed.lua) now always clears the text input buffer when it gains keyboard focus.
