Detekt 2.0 configurations

[chao2zhang]

This is a thread to discuss those configuration names that need to be fixed in a backward incompatible way.

ForbiddenClassName > forbiddenName: This should be renamed to forbiddenNames

Indentation > continuationIndentSize: unused

FunctionParameterNaming > ignoreOverriddenFunctions: deprecated
MemberNameEqualsClassName > ignoreOverriddenFunction: deprecated
LongParameterList > ignoreOverriddenFunction: deprecated
EmptyFunctionBlock > ignoreOverriddenFunctions: deprecated

ForbiddenImport > imports should be forbiddenImports
FunctionOnlyReturningConstant > excludeAnnotatedFunctions should be excludedAnnotatedWith (or something similar)
FunctionOnlyReturningConstant > excludedFunctions to something more meaningful. Maybe even convert to a list.
MagicNumber > ignoreNumbers should be ignoredNumbers
WildcardImport > excludeImports should be excludedImports

ThrowingExceptionsWithoutMessageOrCause, TooGenericExceptionCaught and TooGenericExceptionThrown all define exceptions that should be reported. The config property should be the same in my opinion (currently: exceptionNames vs. exceptions). SwallowedException allows to configure exceptions that should be ignored. The property now is ignoredExceptionTypes. It should be consistent with those above.
