Enhance dead store checker to not flag preincrements to dead variables where the preincrement is a subexpression, e.g. foo(++x); This can cause false negatives, but will remove a whole class of false positives.

Add "category" to BugTypes, allowing bugs to be grouped.
...
Changed casing of many bug names. The convention will be to have bug names (mostly) lower cased, and categories use some capitalization.
