[texworks] SCRIPTING: Get content of specified directory

[Henrik Skov Midtiby]

Hi Paul and others

I have tried to use your code for filename completion for windows. It
it still not tested ...

In addition the script can now complete open environments (which is
determined by looking at the current file from the beginning and to
the cursor location).

The script can be downloaded from
https://github.com/henrikmidtiby/autocompleteForTexworks/blob/master/scripts/autocomplete.js

Any comments and ideas for improvements are appreciated.

Best regards,
Henrik
