PR which adds support for mostly used injection annotations.

Great that you found the time to work on this, much appreciated. Before we can merge the PR, I would need to have a bunch of automated tests for this new symbol provider, as we have for the other symbol providers. That usually involves creating a test project with some sample sources included and writing the unit tests for that, maybe similar to the SpringIndexerBeansTest (but there are others, too).

Sure i will work on it. What do you think about the @= prefix?

[martinlippert]

The prefix in general sounds fine to me, but I always need to play around with early prototypes and see the things in action to really be able to make up my mind about them. But changing that prefix in the future (if necessary) is not a big deal, maybe you should extract that into a constant to make it even easier.
