Is your feature request related to a problem? Please describe.
If a very long string on a password field is inserted, rechecking the field for reading (not just copying, reading by eyes) requires additional inputs ( keyboard or mouse ).
Furthermore, thunder icon of corner of password field usually mask the password when password is quite long.

Describe the solution you'd like
If a password field contains very long password than the WIDTH of the right-side panel of KeeWeb, field line became automatically two-line or three-line when REVEALING is activated.

Describe alternatives you've considered
If password field should be always one-line, please add fade-out effect on the end of strings near field right corner, and please put the thunder icon out of field (e.g. on the right-side of box outline instead of left)
