Changes in Python 3 that made the code choke:
o basestring is merged into str
o print() needs parentesis
o Class inheritance syntax changed
o Abstract baseclass (ABCMeta) syntax changed
o map.iteritems() is replaced by map.items()
o Inconsistent use of tabs and spaces are no longer tolerated

Line numbers of parsed input are now automatically maintained. More
needed data structures are now automatically created in the API header
file.

First time parsing doesn't error out with a syntax error. No usable AST
is produced, strings are not returned from lexer, and AST lists aren't
lists, really.
TEXT:="Hello world!"; had to be excluded from the example, because I
don't get how this could be parsed with the given syntax. There's a
special sequence "all visible characters", but any lexer regex I could
think of will also match the types defining "alphabetic character" and
return the respective tokens (e.g. T_A) or vice-versa, depending on the
order in the lexer input file. I suppose, the only sensible way to
handle this, is to define "all visible characters" by defining the
tokens for the missing characters, and then use them along T_A ... T_Z
or their derived types.

Doesn't successfully parse grammartest.code, yet, it errors out with a
syntax error on whitespace. But at least it compiles and starts.

More code is removed from the special parser directories and centralized
into grammar.py, Cmd.py, and generate-flex-bison.mk.
