New v3.1 beta

Fixes

• Fixed windows legacy builds didn't work because of badly compiled restic legacy binaries
• Always try to decrypt encypted placeholders in config files (fixes authentication failures with previous config files)
• Fix prometheus config migration done once per repository/group
• Another try to make smaller screens usable with GUI (auto scaling depending on screen size)
• Keep log files lowercase as previously

This beta replaces beta 5 which had some compile time problems.

Additional fixes / features:

• GUI: Task creation now asks for user credentials regardless of being elevated or not on Windows (previous elevated UI was hidden)
• GUI: Wait window for task fetching can now be cancelled
• Windows 32 bit builds now include SSLPSK (thanks to @kuba2k2 for making Win32 prebuilt binaries, see kuba2k2/sslpsk3#5)

A new fresh beta release of NPBackup, where we jumped from beta 3 to beta 5 since beta 4 has been a private test release

[EDIT] Binaries retired in favor of beta6 because of compile time errors [/EDIT]

Features

• Zabbix monitoring now fully supports Raw JSON sending

Fixes

• Multiple minor GUI fixes
• GUI Windows UAC elevation should now work properly
• GUI Windows task creation fixes
• Multiple minor fixes

A new fresh beta release of NPBackup.
I know there are still some GUI bugs, especially some ttk theme related ones as well as some scaling issues with linux.
The zabbix code path is also still "very fresh".
Please feel free to open as much issues as required ;)

• Extended Zabbix monitoring capabilities to use TLS certs
• Windows task creation / reading now asks for UAC elevation
