#435 Paste from external application not working on linux

[est31]

Downstream issue: https://github.com/minetest/minetest/issues/373

You can't paste content from an external application to irrlicht (using ctrl+v).

I've tested r5107 with the examples/05.UserInterface program, and tried to paste content from an external application (take firefox as example) into the "Editable Text" box using ctrl+v, nothing happened.

If you let the program print the output of getTextFromClipboard(), you get an empty string.

Pasting content from irrlicht to external applications, or to the same irrlicht instance works, pasting into a second irrlicht instance fails, too.

Thanks for your patch. It's applied to svn r5187 in Irrlicht 1.8 branch an dsvn r5188 in Irrlicht trunk.
