EL method signature inspection

Reports method calls in EL that don't match method-signature constraints in TLD files.

Example Java class:

public class ExampleAction {
  public void goodAction() { ... }
  public void badAction(String str) { ... }
}

Example JSP file:

<jsp:useBean id="example" scope="request" type="org.example.ExampleAction"/>
<f:view>
  <h:commandButton action="#{example.goodAction}"/> // Good: method accepts zero arguments and returns `void`
  <h:commandButton action="#{example.badAction}"/> // Error: method `void badAction(String)` returns `java.lang.String` type instead of `void`
</f:view>
