Various improvements related to the recent implementation of temporary passwords

for mail shares:

1- Changes style of "forgot password?" and "Back" button
2- Adds information about share password's expiration time in the emails sent.
3- Shows password expiration time in the Share menu
4- Fixes an issue when the message "Password expires..." would be shown for non email share types (which don't have temporary passswords)
5- At share's creation, password should only be sent when it's a permanent one
