More complete editing for existing shares

[shelvacu]

is your feature request related to a problem? Please describe.

This happened to me just now:

• create share set to 1d expiration
• realize "actually I want to set to to 1 week"
• go to ?shares
• the only buttons are for +1m or +1hr, and I didn't really want to click 1hr 168 times

I popped open the console and edited in the button I wanted, but it would be nice if there was a proper way.

Describe the idea / solution you'd like

An edit screen that has all the same fields as the screen for creating a share:

• name
• source
• password
• expiry (with input for days)
• perms

Describe any alternatives you've considered

deleting and re-creating the share: totally reasonable workaround, but a proper edit function would be nice

ye, first idea that comes to mind is the 1h button could be kept as a shortcut, but 1min replaced with edit to do soemthing like this -- it would definitely allow editing expiry time, and probably also password, maybe also name/source/perms but will have to check if that's safe with multiprocessing -- will be a while until i can look at this, maybe month(s) but will do
