codeintel: Extra logging for codeintel request timing information

To use: run komodo with
  komodo --raw -log codeintel.komodo.timing:INFO

Also change request timeout to 5 minutes - that's still way too long, but
less obscene than 30 minutes.

(integrated from komodo (trunk) change 82769 by marky)
