Lambda parameter type can be specified

Reports lambda parameters that do not have their type specified and suggests adding the missing type declarations.

Example:

Function<String, Integer> length = a -> a.length();

After the quick-fix is applied:

Function<String, Integer> length = (String a) -> a.length();

This inspection depends on the Java feature 'Lambda expressions' which is available since Java 8.
