check collectgroup for remote GLI

[kjdon]

collect groups now work properly for local greenstone and gli.

Collect groups is a folder in the collect directory, with an etc directory, with collect.cfg file with 'collectgroup true' in it. then you can put collections in the subfolder and they will be grouped together.

We need to check remote gli to see if it can handle this. I think at the moment it won't because all the commands get a collection name - nothing to say its in a subdir.

Do we want to make this work for this release or the next one?

Updated ZipCollectionConfigurations.java and ZipTools.java to handle zipping up collection groups with collections. Need to still pass around the group-qualified-collection names to the various remote GS methods.

Need to check that collectdir can be located elsewhere. Last time I tested this with Greenstone 2.83 for someone using Greenstone in R-block and who needed this feature, it seemed to ignore the collectdir value. (Is it still the llssite and glisite config files where the collectdir can be specified?)

Replying to ak19: The last comment was meant for ticket #152 "Allow different paths to collect dir".

At last, Remote Greenstone can now handle the collectgroup feature that Katherine had implemented. Tested on Windows and Linux.
