Supports single quote strings in AutoItLexer

Fix for issue #1663

[Anteru]

Can you please add a test for it?

[trdean1]

Done - I have added a line to tests/examplefiles/autoit/autoit_submit.au3 that tests this case and updated the corresponding output file after verifying the output from pytest was correct.

Thanks. Something doesn't look right though: The ' appears both as Token.String, and then again with the rest of the string. That doesn't seem quite right to me, as you'd get ''boo; bar; "baz"'' when you paste them back together. Can you please double check that the output looks correct?

I think it looks correct to me. The ''s on line 177 of autoit_submit.au3.output are just displaying the token as a string. Compare to lines 14-16 which holds the output of "http://localhost:8080". This becomes

'"'   Literal.String
'http://localhost:8080'  Literal.String
'"'   Literal.String

Ah, you're right, my bad! Thanks, merged for the next release!
