Removed all @category, @package, and @subpackage annotations
Removed all @category, @package, and @subpackage annotations

- Per zendframework/zf2#2743, and following on zendframework/zf2#2953 and discussion on the ML
- Also removes empty docblocks, and empty lines at the end of docblocks
- Library only; phpdoc is never run on tests anyways, and did not want to
  potentially create breakage due to test expectations that relied on
  annotations. At this time, all tests pass.
