change the key from const char * to QByteArray

if trGettext() gets called with a *text that resides
in the stack, the QHash will return incorrect values after
the second call of trGettext() with that *text.

Example (assuming nothing has been translated):

void func(const char *text) {
        char *translated = trGettext(text);
        doSomethingWith(translated);
}

func("foo"); (1)
func("bar"); (2)

(1) *translated is "foo"
(2) *translated should be "bar" but is "foo" because
    the key (const char*) points to the value "foo"
    which has been set in the previous call (1).
