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).

Just to make sure there's no confusion - we are NOT calling gettext. We
are calling tr from a gettext like interface.

Instead use a hash to cache the translations (and allow for the ability to
clear the hash so we can even switch translations at runtime...).
Now Qt will keep track of the memory and release it for us when we are
done with it.
This avoids the memory leak introduced in commit 4ecb35bf5ff2 ("Make a
copy of the translated text").
