Reduced code parsing performance after upgrading to Ubuntu 14.04

[Drew Noakes]

Deleting the ~/.cache/kdevduchain directory and restarting kdevelop seems
to have addressed the issue. The directory contained around 500MB of cache
before, and after reparsing my main project it's at 41MB.

Thanks all for your help. I'm really glad to have kdevelop back and working
well. It's a great IDE for C++.
