kdevelop2 doesn't compile under kde3

[Ralf Nolden]

Hi there, 

due to *our* latest changes - the autocompletion in the classdialog - 
kdevelop2 doesn't compile under KDE 3 anymore. I fixed Ellis' changes by 
using #ifdef's so they compile under both systems again, just the 
autocompletion needs a fix.

Thanks,

Ralf
