#361 CamelCase completion

[Stefan C]

I miss CamcelCase completion

for instance if I have a class "class CamelCaseImplFinder" I cannot type "CCIF" then hit ctrl+space and it will find the CamelCaseImplFinder class.
It would also be nice if it would treat _as a CamelCase.. it a function named "my_wonderful_method" can be found via MWM ctrl+space
