Bug was causing infinite private messages sent!

[Andrea Scarpino]

Well... as per subject, it seems that during my port from Qt4, I caused an 
infinite loop that occurs when sending a private message using TwitterApi (so, 
affected microblogs are Twitter and GNU Social). The real issue is that the 
private messages are sent in background until you close Choqok (!!!).

More specifically, with commit bfbbf7cb I migrated TwitterAPI away from KDialog 
and I replaced slotButtonClicked() method with QDialog::accept(). 
Unfortunately I didn't notice that postCreated() method was calling 
QDialog::accept() and this caused the infinite loop.

I don't understand why postCreated() calls accept() and then I just removed 
that invocation with commit fe405dc.

I suppose we should release Beta 2 ASAP.
