Add memory of last page configuration on client

[openlowcode]

when doing 'back' on the client, user should be brought back to the previous page with the configuration at the time it left the page. This includes:

• position in the page (scrollbar). Something simple and robust should be implement in case of window resize in the meantime.
• selection of lines in tables
• ordering of columns
• inline data that was put in the page (e.g. search or report result), with a warning that data is from the past.
