a8204385c3 Adds fix for __init_subclass__ bug. (#2390) 
* Adds fix for __init_subclass__ bug.

* Adds test case.

* Move test on name.

I think it makes more sense here, alongside the other "special" method names.

cac261858c Python: Don't report mutable parameters that are in fact immutable. 
Fixes #1832.

In the taint sink, we add an additional check that the given control-flow node
can indeed point to a value that is mutable. This takes care of the guard on the
type.

If and when we get around to adding configurations for all of the taint
analyses, we may want to implement this as a barrier instead, pruning any steps
that go through a type test where the type is not mutable.

457794e030 Python: Consistenly use parameter instead of argument in docs 
The Python 3 FAQ states that this is the right thing [0]

It sadly doesn't align 100% with PEP8, which calls them for "arguments" [1], but
after discussion with Taus, we decided to go with "parameter" everywhere to be
consistent.

d273974045 Python: Don't flag return procedure_call() in __init__ as error 
This commit fixes the results for
0d8a429b7e/files/mayaTools/cgm/lib/classes/AttrFactory.py (L90)

```
def __init__(...):
    if error_case:
        return guiFactory.warning(...)
```

that was wrongly reporting _Explicit return in __init__ method._ as an error.
