Add template support to the code generation pref panel for getter and setter method bodies.

* <p>The returned string is unformatted and not indented.
	 * <p>Exception types and return type are in signature notation. e.g. a source method declared as <code>public void foo(String text, int length)</code>
	 * would return the array <code>{"QString;","I"}</code> as parameter types. See {@link org.eclipse.jdt.core.Signature}
	 * 
	 * @param cu The compilation unit to which the method belongs. The compilation unit does not need to exist.
	 * @param declaringTypeName Name of the type to which the method belongs. For inner types the name must be qualified and include the outer
	 * types names (dot separated).
	 * @param methodName Name of the method.
	 * @param paramNames Names of the parameters for the method.
	 * @param excTypeSig Throwns exceptions (Signature notation)
	 * @param retTypeSig Return type (Signature notation) or <code>null</code>
	 * for constructors.
	 * @param overridden The method that will be overridden by the created method or
	 * <code>null</code> for non-overriding methods. If not <code>null</code>, the method must exist.
	 * @param lineDelimiter The line delimiter to be used
	 * @return Returns the constructed comment or <code>null</code> if
	 * the comment code template is empty. The returned content is unformatted and not indented (formatting required).
