Prefixing issues

[TwitchBronBron]

There are several issues with the prefixer that need to be addressed:

• namespace-relative function refs in typedefs are not properly handled. (should use dot notation, and this one has the wrong prefix...)

• Should handle roSGNode* component names

• Should handle any types referenced in brsdoc comments

• comments are incorrectly above a namespace instead of the function they were originally attached to
