[PATCH v3 07/19] rv/rvgen: fix typos in automata and generator docstring and comments

[Wander Lairson Costa]

Fix two typos in the Automata class documentation that have been
present since the initial implementation. Fix the class
docstring: "part it" instead of "parses it". Additionally, a
comment describing transition labels contained the misspelling
"lables" instead of "labels".

Fix a typo in the comment describing the insertion of the initial
state into the states list: "bein og" should be "beginning of".

Fix typo in the module docstring: "Abtract" should be "Abstract".

Fix several occurrences of "automata" where it should be the singular
form "automaton".
