fix 2 not working buttons:

• show the brain key
• confirm the password (in the password change section in options)

General

1. Go to: https://wallet.bitshares.org/#/settings/password

and try entering the current password
the button does not work there.
but the event on the ENTER key works
need to create a bind on the button.

2. Go to: https://wallet.bitshares.org/#/settings/backup

choose:
"Create brainkey backup"
and try entering the current password for show brainkey
the button does not work there.
but the event on the ENTER key works
need to create a bind on the button.

also a small fix with a pop-up notification.
