split_suffix in RecurrentStack does not handle names with multiple # correctly

[rustonaut]

Hy,

the "split_suffix" code:

    @staticmethod
    def split_suffix(name):
        # Target name with suffix to the correct layer
        name_level = name.split(RECURRENTSTACK_SEPARATOR)
        if len(name_level) == 2 and name_level[-1].isdigit():
            name = RECURRENTSTACK_SEPARATOR.join(name_level[:-1])
            level = int(name_level[-1])
        else:
            # It must be from bottom layer
            level = 0
        return name, level

won't work correctly if the name hase more than one # ("#"==RECURRENTSTACK_SEPARATOR),
it will see that len(name_level) is > 2 and set the level to 0 (but on the other hand it reconstructs the name in the first line of the if body as if it could have had a len > 2.

PS:
I will send in a fix using .rsplit(..., 1) (split only one time first occurrence from right)
