Subsurface creates a lot of singleton instances on demand, but nothing
ever deleted them. Since they are singletons, these memory allocations
are technically not leaks. However, they clutter the output in valgrind
and other memory analysers, hiding the real issues.
The solution is to delete these items at exit. For the models and for
gettextFromC, the solution is to use a QScopedPointer, which will delete
its payload when it gets destroyed. For the dialogs and other widgets,
we can't do that: they need to be deleted before QApplication exits, so
we just set the parent in all of them to the main window.

Interpreting UTF8 encoded strings using tr() instead of trUtf8()
and encoding the string back to utf8 again leads to serious encoding
errors.

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").

Otherwise the translation will get freed (and often reused) before it
makes it to the screen.
The problem with this is that it leaks memory for every translation.
