make_enum doesn't enforce "valid Python identifiers" limitation

[ssteinerX]

>>> Foo = flufl.enum.make_enum("Foo", "ham spam eggs" )
>>> Foo.ham
<EnumValue: Foo.ham [int=1]>
>>> Doo = flufl.enum.make_enum("Foo", "1 2 3")
>>> Doo
<Foo {1: 1, 2: 2, 3: 3}>
>>> Doo.1
  File "<stdin>", line 1
    Doo.1
        ^
SyntaxError: invalid syntax
>>> Doo(1)
<EnumValue: Foo.1 [int=1]>

Not sure whether this is worth dealing with, more of an observation.

Yeah, probably worth fixing, low priority though. :)
