Unload opened image & preview in single tab mode

[Beep6581]

Originally reported on Google Code with ID 654

This is a request for new feature that may be useful for better management of memory
consumption. 

Multitab mode allows to close open image and free RAM that may be used for batch queue
processing. This option is not available when single tab editor is used. the new feature
request is to allow to close the image open in a single tab editor to free the system
resources.

Current workaround - restart RT and process images in the batch queue without opening
any images in the single tab editor.

Good idea. How about not having an additional button but automatically close the pic
if you switch to thumb or batch tab?

I think such automatic closing of opened image may be unexpected. User may want to quickly
switch to a different tab just to look something up and come back, not intending to
close the open image.

The idea was more to close the image, but keep the selection. So the image would be
reloaded if the users comes back to the edit tab. Reload takes a bit longer, but saves
RAM.

However from users point of view it would be not obvious that he has to close anything
at all to not have a crash. Also there would have to be blocks to not have him open
any image while the batch queue is processing. All not very elegant.

I imagined this is a manual step in the workflow, but I understand that you are trying
to make it transparent to the user. 

I have an idea - when Queue is about to start and at least one image is opened there
may be a prompt asking if user would like open images to be closed to conserve system
resources. If user selects to close, then all open images will be auto-closed before
starting the queue. This prompt should provide 3 options - 
1. Close open images, - close images and start queue
2. Don't close open images, - don't close images and start queue
3. Cancel - close the prompt, don't start the queue

Yet another option, probably a smoother one, could be a checkbox in the batch queue
Tab - "close open images before queue starts". It is upto a user then to keep opening
images when queue is running...

Since we hopefully found a remedy using the linker/bootini switches... shall we puts
thi on hold for a couple days to see if it's still necessary?
