[texworks] UPDATE: New Windows version - please test

[Stefan Löffler]

Hi,

I've just posted a new test build. The dialog issue should hopefully be
resolved now. On Windows Vista and later, the native dialogs are used,
while on XP and before, the Qt dialogs are used (due to the missing
"bookmarks" in the native XP dialogs).

Please test and see if this works as expected.

Thanks,
Stefan

PS: The update to the scripting functions system() and launchFile() are
included in this build, so some scripts may fail. This is easily
corrected, though (see separate message).
