Display keystore password when exporting it

[KobeW50]

Type

Issue

When you export the keystore, it does not show the password that it has.

Although it normally has the default one, it can have a different one.

Also, because it doesn't show the password when exporting it, the password prompt when importing it is confusing. It made me think that I am setting a new password.

Feature

When you press the "Export Keystore" button a pop-up will appear that displays the password for the Keystore.

Motivation

It is useful to tell/remind the user the password of the keystore.
