Some improvement ideas

[audetto]

Hi,

just writing a couple of things I would like to do and propose as pr, to see if there are any comments or objections

• move the .csv file in a separate folder ".poolviewer" as a good Linux tradition
• backup. I would feel safer if there was a backup each time the master database is updated. Now I do it manually and I keep all past versions. So I would propose to save the main file with a time stamp in the same ".poolviewer" folder. Maybe have this as an option in the settings
• time sync: option to sync watch time on download
• allow all tables to be sortable. (this is almost done, need to fix an issue with selection)
• gap -> lanes (as Estimate missing lengths feature #19)

turns out that first is not useful, as the user can already specify the location (thought I would need it for the 2nd).

I've proposed an implementation of the 2nd with an option to enable if desired.

1. Agree on the first point though, I'd been meaning to add an initial 'wizard' dialog to set sane initial settings but haven't done so yet.
2. yea of little faith. :) yeah makes sense, I just keep a few copies lying around.
3. pretty straightforward to do that, not sure whether to do it automatically on each download or just add a set watch settings dialog for weight, pool, time etc.
