Potential new inspections (based on old ideas)

[mwz]

Here's a list of not implemented inspections I removed in #281.

It would be good to review this list and prioritise based on usefulness and which ones we would like to see implemented first.

1. AbstractTrait
2. AbstractValueInTrait
3. ChainedPackageClause
4. ClassExtendsApp
5. DefaultArgUse
6. EqualInspection
7. HardCodedWindowsFileSeparator
8. HashcodeInspection
9. MethodWithUnitReturnIsParameterless
10. NoClone
11. NoSuperClone
12. OptionGetGetOrElse
13. SetSeqToDistinctStub
14. UnusedLocalVal
15. UppercaseLChecker
16. UselessObjectVisibility
17. VarFields
18. collections/ExistsIncompatibleType
19. collections/FilterDotSizeComparison
20. collections/ListTail
21. exception/CaughtExceptionImmediatelyRethrown
22. exception/ProhibitedExceptionThrown
23. matching/FruitlessMatch
24. math/IntDivisionAssignedToFloat
25. naming/FieldNames
26. naming/VariableNames
27. option/InexhausticOptionMatch
28. option/OptionComparison
29. option/OptionHead
30. string/NegativeStringMultiplication
31. unneccesary/UnnecessaryCatchBlock
32. unneccesary/UnnecessaryStoreBeforeReturn
33. unneccesary/UnnecessarySubstring

I would also be up for implementing some of these. But I have no idea regarding prioritization.

I don't think there is any specific priority. Is there anything particular on that list that you feel strongly about?
