Patch: TODO highlighting in comments

[Syron]

> Then what is it?
In my own opinion the problem reporter is the right location, because 
the TODOs are hints that some functionality may not be given or that 
some functions make problems. This is highly context sensitive, as the 
problem reporter is.
Whenever I write code, I only need the TODOs from the current context - 
they're less important than parsing problems, but they can still lead to 
problems if you don't know them.
