Provide a way to reload conf

[gleu]

We probably should have a menu item "Reload configuration" in the server contextual menu.

Probably a good idea, yes. But we also need to detect and tell the user if we had any error doing the reload, so we can't just send the signal!

The only error we can get is if the user is not a PostgreSQL superuser. If the user tried to reload some changes that should have required a restart, we won't know. The only way to get that kind information is from the log files.

Why is this useful? The only places in pgAdmin where you can change the server config already have reload buttons.

I have a customer who works a lot with pgAdmin. He changed his config file, and wanted to reload the server. He could have used the menu item in the Windows menu, but didn't remember it. He went to pgAdmin, could not use the config editor (he doesn't have the adminpack module installed), but went directly to pgAdmin and tried the server contextual menu... and found nothing.

Probably not the best example. But I was also surprised we didn't have that contextual menu.
