Open files in read mode and re-read the file after it has been changed

[julbts@…]

Open the files in "read" mode, so they can also be accessed by other programs and it is allowed to write the file while it is already opened by Lucide. If the file has changed it has to be re-read! This is needed to use it as PDF-Viewer when someone creates PDF files with VTEX/2 (LaTeX).

You have to compare the last saved timestamp with the current timestamp when the Lucide window will be activated. If you have a background thread that will check the timestamps in the background this would be an option too. Look at the GSView source, which is supporting this feature since ages.

We use poppler library for reading pdf's, so we open files as poppler does it.

Moving to 2.0, we can think about that when we are bored.
