UInstaller v2 brings in many stability and usability improvements, as well as some new features!

Changelog:

UInstaller now uses uz on both Windows and Linux to extract maps when installing Unreal Tournament.
Map decompression process now happens in a separate dialog window, which fixes the "app looking frozen" issue.
- When the decompression succeeds, it will close down on its own, to continue with the rest of the installation.
- When the decompression fails, it will notify the user, and make them close the dialog by themselves instead.
- Also removes the installation folder when decompression fails.
Disable the Start button once the installation is successful, until the user picks up another path.
Fixed the awkward "Cannot find file" error once UInstaller installs a game then the user asks to install another, despite the file existing.
One can now install different versions of the 227/469 community patches.
- The selectable patches are limited to 227k_12 and later (when they exist) for Unreal Gold and 469d and later for Unreal Tournament.
- The main reason behind this is that they are the patches that have zipped versions.
Added installation support for UT 469e_RC7.
Added ability to install the Fusion map pack for Unreal Gold.
On Linux, UInstaller will warn about needing Wine to play the games when the community patches aren't installed.

Hotfix

[06.03.2025] - Windows version is updated to fix the "Missing libcrypto-3-x64.dll" issue. You can either redownload the updated 7z archive, or you can install Windows binaries for OpenSSL on your computer. Since OpenSSL is probably installed by default on any Linux distro, I didn't find the need to update UInstaller there.
