Docblock param description wrong for utf8_accents_to_ascii() in phputf8

[gnanet]

string/src/phputf8/utils/ascii.php

Line 145 in c7a9330

* @param int (optional) -1 lowercase only, +1 uppercase only, 1 both cases

According the sourcecode, you may skip the parameter, or you have to set the parameter to zero for translate both cases, NOT 1 as declared in the description of the function.
See:

if($case <= 0){
        if ( is_null($UTF8_LOWER_ACCENTS) ) {
...
if($case >= 0){
        if ( is_null($UTF8_UPPER_ACCENTS) ) {
...

So the right parameter description would be:

 * @param int (optional) -1 lowercase only, +1 uppercase only, 0 both cases
