Issue with AutoIT Parser

[trdean1]

I've noticed something the AutoIT parser gets wrong. The following line of AutoIT code

$foo = 'bar; baz'

will get tokenized as

[(Token.Name.Variable, '$foo'),
 (Token.Text, ' '),
 (Token.Operator, '='),
 (Token.Text, ' '),
 (Token.Text, "'"),
 (Token.Name, 'bar'),
 (Token.Comment.Single, "; baz'\n")]

The correct tokenization should be

[(Token.Name.Variable, '$foo'),
 (Token.Text, ' '),
 (Token.Operator, '='),
 (Token.Text, ' '),
 (Token.Literal.String, '"'),
 (Token.Literal.String, 'bar; baz'),
 (Token.Literal.String, '"'),
 (Token.Text, '\n')]

I noticed the tokenization is done correctly if the string is enclosed in double quotes rather than single quotes, but both should be valid autoit syntax
