Requiring explicit save on item create can lead to data loss on timeout

From a forum post by reyawn:
"I generated the password. I entered it in the web form, filled everything in, submitted the form, and then went back to the phone. Keyring had timed out [...] I didn't get to saving the new entry in Keyring yet, and upon unlocking it again I discovered that it was lost!"

I required explicit save to avoid problems with duplicate titles, but it would be better to check that on blur of the title field.
