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.
We

1. AbstractValueInTrait
2. ChainedPackageClause
3. ClassExtendsApp
4. DefaultArgUse
5. EqualInspection
6. HardCodedWindowsFileSeparator
7. HashcodeInspection
8. MethodWithUnitReturnIsParameterless
9. NoClone
10. NoSuperClone
11. OptionGetGetOrElse
12. SetSeqToDistinctStub
13. UnusedLocalVal
14. UppercaseLChecker
15. UselessObjectVisibility
16. VarFields
17. collections/ExistsIncompatibleType
18. collections/FilterDotSizeComparison
19. collections/ListTail
20. exception/CaughtExceptionImmediatelyRethrown
21. exception/ProhibitedExceptionThrown
22. matching/FruitlessMatch
23. math/IntDivisionAssignedToFloat
24. naming/FieldNames
25. naming/VariableNames
26. option/InexhausticOptionMatch

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?
