[Passwordsafe-linux] Releasing PasswordSafe 1.19.0 [wx]

[pwsafe.org <ro...@pw...>]

Hi,

Although there are still open issues and work-in-progress, I've decided to
release a new wx version to track the latest Windows release, Thanks to all
for your contributions!

Any help in setting up a flatpak update appreciated.

Cheers,

Rony
