Ensure that SciJava-common's own annotations are indexed

... even if the tests are not run (which would trigger the
EclipseHelper)...

We still use SezPoz, but will switch in the next commit.

Switch to our own annotation indexer

Stop using CheckSezPoz

We worked around SezPoz problems in conjunction with Eclipse' failure to
run annotation processors when required for a long time.

Based on what we learnt with CheckSezPoz, SciJava-common's very own
annotation indexer already implements the same functionality, rendering
the former obsolete.

Combine annotation indexes by simple concatenation

... now that they are written out as plain, concatenable JSON...

Deprecate the SezPoz checker

We no longer need it; its functionality is implemented by the
EclipseHelper class now.

Remove unnecessary @SuppressWarning

On the MacOSX machine where this developer developed the annotation
processor, Eclipse marked these classes as restricted (but they
actually should not be).
