Last change on this file since e5d8d21 was e046390, checked in by Wilmer van der Gaast <wilmer@…>, at 2009-10-10T23:25:54Z

Make purple use BitlBee's event handling API. Since the APIs never really
diverged too much this is fairly transparent. I did rename and redefine
GAIM_INPUT_* variables to really make it work without adding another stupid
layer in between.

One problem left, the new libpurple input API doesn't care about return
values. Fixing that in the next CL.
